********** REPORT OF PROTEIN ANALYSIS  by the WHAT IF program **********
************************************************************************

Date : 2024-11-24
This report was created by WHAT IF version WHATCHECK15.0

This document is a WHAT_CHECK 14.0 report for a PDB-file. Each reported
fact has an assigned severity, one of:

error  : Items marked as errors are considered severe problems requiring
         immediate attention.
warning: Either less severe problems or uncommon structural features. These
         still need special attention.
note   : Statistical values, plots, or other verbose results of tests and
         analyses that have been performed.

If alternate conformations are present, only the first is evaluated. Hydrogen
atoms are only included if explicitly requested, and even then they are not
used in all checks. The software functions less well for non-canonical amino
acids and exotic ligands than for the 20 canonical residues and canonical
nucleic acids.

Some remarks regarding the output:

Residues/atoms in tables are normally given in a few parts:

A number. This is the internal sequence number of the residue used by WHAT IF.
    The first residues in the file get number 1, 2, etc.
The residue type. Normally this is a three letter amino acid type.
The sequence number, between brackets. This is the residue number as it was
    given in the input file. It can be followed by the insertion code.
The chain identifier. A single character. If no chain identifier was given in
    the input file, this will be a minus sign or a blank.
A model number. If no model number exists, like in most X-ray files, this will
    be a blank or occasionally a minus sign.
In case an atom is part of the output, the atom will be listed using the PDB
    nomenclature for type and identifier.

To indicate the normality of a score, the score may be expressed as a Z-value
   or Z-score. This is just the number of standard deviations that the score
   deviates from the expected value. A property of Z-values is that the
   root-mean-square of a group of Z-values (the RMS Z-value) is expected to be
   1.0. Z-values above 4.0 and below -4.0 are very uncommon. If a Z-score is
   used in WHAT IF, the accompanying text will explain how the expected value
   and standard deviation were obtained.
The names of nucleic acids are DGUA, DTHY, OCYT, OADE, etc. The first character
   is a D or O for DNA or RNA respectively. This circumvents ambiguities in the
   many old PDB files in which DNA and RNA were both called A, C, G, and T.

# 1 # Note: Introduction
WHAT CHECK needs to read a PDB file before it can check it. It does a
series of checks upon reading the file. The results of these checks are
reported in this section (section 2.1). The rest of the report will be more
systematic in that section 2.2 reports on administrative problems. Section
2.3 gives descriptive output that is not directly validating things but
more telling you how WHAT CHECK interpreted the input file. Section 2.4
looks at B-factors, occupancies, and the presence/absence of (spurious)
atoms. Section 2.5 deals with nomenclature problems. Section 2.6 deals with
geometric problems like bond lengths and bond angles. Section 2.7 deals with
torsion angle issues. Section 2.8 looks at atomic clashes. Section 2.9 deals
with packing, accessibility, etc, issues. Section 2.10 deals with hydrogen
bonds, ion packing, and other things that can be summarized under the common
name charge-charge interactions. Section 2.11 gives a summary of whole report
and tells you (if applicable) which symmetry matrices were used. Section 2.12
tells the crystallographer which are the things most in need of manual
correction. And the last section, section 2.13, lists all residues sorted
by their need for visual inspection in light of the electron density.

# 5 # Warning: Problem detected upon counting molecules and matrices
The parameter Z as given on the CRYST card represents the molecular
multiplicity in the crystallographic cell. Normally, Z equals the number of
matrices of the space group multiplied by the number of NCS relations. The
value of Z is multiplied by the integrated molecular weight of the molecules
in the file to determine the Matthews coefficient. This relation is being
validated in this option. Be aware that the validation can get confused if
both multiple copies of the molecule are present in the ATOM records and
MTRIX records are present in the header of the PDB file.
 
 Space group as read from CRYST card: P 21 21 2
 Number of matrices in space group: 4
 Highest polymer chain multiplicity in structure: 1
 Highest polymer chain multiplicity according to SEQRES: 1
 No explicit MTRIX NCS matrices found in the input file
 Value of Z as found on the CRYST1 card: 0
 Z, symmetry, and molecular multiplicity disagree
 Could it be that Z must be: 4
 
# 6 # Error: Matthews Coefficient (Vm) very high
 
The Matthews coefficient [REF] is defined as the density of the protein
structure in cubic Angstroms per Dalton. Normal values are between 1.5
(tightly packed, little room for solvent) and 4.0 (loosely packed, much
space for solvent). Some very loosely packed structures can get values a bit
higher than that.
 
Numbers this high are almost always caused by giving the wrong value for Z
on the CRYST1 card (or not giving this number at all).
 
 Molecular weight of all polymer chains: 63311.398
 Volume of the Unit Cell V= 797042.812
 Space group multiplicity: 4
 No NCS symmetry matrices (MTRIX records) found in PDB file
 Matthews coefficient for observed atoms and Z is high: Vm= 12.589
 A few residues have missing atoms that did not enter the Vm calculation
 No Matthews coefficient given in REMARK 280
 Could it be that Z must be: 4
 This number is the multiplication of the spacegroup and NCS symmetry count
 Matthews coefficient for observed atoms and corrected Z: Vm= 3.147
 
# 7 # Note: Z missing on CRYST1 card
The messages above seem likely caused by the fact that Z is missing from the
CRYST1 card.
 
# 8 # Note: All atoms are sufficiently far away from symmetry axes
None of the atoms in the structure is closer than 0.77 Angstrom to a proper
symmetry axis.
 
# 9 # Note: Chain identifiers OK
WHAT CHECK has not detected any serious chain identifier problems. But be
aware that WHAT CHECK doesn't care about the chain identifiers of waters.
 
# 10 # Warning: Ligands for which a topology was generated automatically
The topology for the ligands in the table below were determined
automatically. WHAT CHECK uses a local copy of the CCP4 monomer library to
generate topology information for ligands. Be aware that automatic topology
generation is a complicated task. So, if you get messages that you fail to
understand or that you believe are wrong, and one of these ligands is
involved, then check the ligand topology entry first. This topology is either
present in the monomer library, or as a libcheck-generated file in the local
directory.

# 11 # Warning: Covalently bound ligands
The ligands in this table are covalently bound to something else. It is
already difficult to automatically generate topologies for ligands,
but when they are covalently bound to something it becomes even more
complicated to do everything right. So, if you get weird error messages
that seem related to this covalent bond, then please feel free to
ignore those, or even better, make a topology entry by hand.
 
The comment `Other ligand` indicates that the covalent bond is to another
ligand. In that case you might want to convert the two ligands into one
bigger ligand.

# 12 # Note: No strange inter-chain connections detected
No covalent bonds have been detected between molecules with non-identical
chain identifiers.
 
# 13 # Note: No duplicate atom names in ligands
All atom names in ligands (if any) seem adequately unique.
 
# 14 # Note: In all cases the primary alternate atom was used
WHAT CHECK saw no need to make any alternate atom corrections (which means
they either are all correct, or there are none).
 
# 15 # Note: No residues detected inside ligands
Either this structure does not contain ligands with amino acid groups inside
it, or their naming is proper (enough).
 
# 16 # Note: No attached groups interfere with hydrogen bond calculations
It seems there are no sugars, lipids, etc., bound (or very close) to atoms
that otherwise could form hydrogen bonds.
 
# 17 # Note: No probable side chain atoms with zero occupancy detected.

# 22 # Note: Ramachandran plot
In this Ramachandran plot x-signs represent glycines, squares represent
prolines, and plus-signs represent the other residues. If too many
plus-signs fall outside the contoured areas then the molecule is poorly
refined (or worse). Proline can only occur in the narrow region around
phi=-60 that also falls within the other contour islands.
 
In a colour picture, the residues that are part of a helix are shown in blue,
strand residues in red. Preferred regions for helical residues are drawn in
blue, for strand residues in red, and for all other residues in green. A full
explanation of the Ramachandran plot together with a series of examples can
be found at the WHAT CHECK website [REF].

This is the secondary structure according to DSSP. Only helix (H), overwound
or 3/10-helix (3), strand (S), turn (T) and coil (blank) are shown [REF].
All DSSP related information can be found at swift.cmbi.ru.nl/gv/dssp/
This is not really a structure validation option, but a very scattered
secondary structure (i.e. many strands of only a few residues length, many
Ts inside helices, etc) tends to indicate a poor structure. A full
explanation of the DSSP secondary structure determination program together
with a series of examples can be found at the WHAT CHECK website [REF].

The atoms listed in the table below are missing from the entry. If many atoms
are missing, the other checks can become less sensitive. Be aware that it
often happens that groups at the termini of DNA or RNA are really missing,
so that the absence of these atoms normally is neither an error nor the
result of poor electron density. Some of the atoms listed here might also be
listed by other checks, most noticeably by the options in the previous
section that list missing atoms in several categories. The plausible atoms
with zero occupancy are not listed here, as they already got assigned a
non-zero occupancy, and thus are no longer 'missing'.

In principle, B-factors can have a very wide range of values, but in
practice, B-factors should not be zero while B-factors above 100.0
are a good indicator that the location of that atom is meaningless. Be
aware that the cutoff at 100.0 is arbitrary. 'High' indicates that atoms
with a B-factor > 100.0 were observed; 'Zero' indicates that atoms with
a B-factor of zero were observed.

# 30 # Note: C-terminus capping
The residues listed in the table below are either C-terminal or pseudo
C-terminal (i.e. last residue before a missing residue).
In X-ray the coordinates must be located in density. Mobility or disorder
sometimes cause this density to be so poor that the positions of the atoms
cannot be determined. Crystallographers tend to leave out the atoms in such
cases. In many cases the N- or C-terminal residues are too disordered to see.
In case of the N-terminus, you can often see from the residue numbers if
there are missing residues; at the C-terminus this is impossible. Therefore,
often the position of the backbone nitrogen of the first residue missing
at the C-terminal end is calculated and added to indicate that there
are missing residues. As a single N causes validation trouble, we remove
these single-N-residues before doing the validation. If this happened,
the label -N is added to the pseudo C-terminus. Other labels can be +X
in case something weird is bound to the backbone C, or +OXT if a spurious
OXT atom is found. -OXT indicates that an expected OXT is missing. 'Swap'
means that the O' and O'' (O and OXT in PDB files) have been swapped in
terms of nomenclature. 'Bad' means that something bad happened that WHAT IF
does not understand. In such cases you might get three residue numbers in
square brackets; one of those might be what WHAT IF had expected to find,
but then it also might not). In case of chain breaks the number of missing
residues is listen in round brackets. OK means what it suggests...
 
Be aware that we cannot easily see the difference between these errors and
errors in the chain and residue numbering schemes. So do not blindly trust
the table below. If you get weird errors at, or near, the left-over
incomplete C-terminal residue, please check by hand if a missing Oxt or
a removed single N is the cause. Also, many peptidic ligands get the same
chain identifier as the larger protein they are bound to. In such cases there
are more than one C-termini and OXTs with the same ID. WHAT IF gives some
random warnings about these cases. So, don't take everything at face value,
but think for yourself.

# 31 # Note: Weights administratively correct
All atomic occupancy factors ('weights') fall in the 0.0--1.0 range, which
makes them administratively correct.
 
# 32 # Note: Normal distribution of occupancy values
 
The distribution of the occupancy values in this file seems 'normal'.
 
Be aware that this evaluation is merely the result of comparing this file
with about 500 well-refined high-resolution files in the PDB. If this file
has much higher or much lower resolution than the PDB files used
in WHAT CHECK's training set, non-normal values might very well be perfectly
fine, or normal values might actually be not so normal. So, this check is
actually more an indicator and certainly not a check in which I have great
confidence.
 
# 33 # Note: All occupancies seem to add up to 0.0 - 1.0.
In principle, the occupancy of all alternates of one atom should add up till
0.0 - 1.0. 0.0 is used for the missing atom (i.e. an atom not seen in the
electron density). Obviously, there is nothing terribly wrong when a few
occupancies add up to a bit more than 1.0, because the mathematics of
refinement allow for that. However, if it happens often, it seems worth
evaluating this in light of the refinement protocol used.
 
# 34 # Warning: What type of B-factor?
WHAT CHECK does not yet know well how to cope with B-factors in case TLS has
been used. It simply assumes that the B-factor listed on the ATOM and HETATM
cards are the total B-factors. When TLS refinement is used that assumption
sometimes is not correct. The header of the PDB file states that TLS groups
were used. So, if WHAT CHECK complains about your  B-factors, while you think
that they are OK, then check for TLS related B-factor problems first.
 
Number of TLS groups mentione in PDB file header: 0
 
Temperature not mentioned in PDB file. This most likely means
that the temperature record is absent.
Room temperature assumed
 
# 35 # Note: Number of buried atoms with low B-factor is OK
For protein structures determined at room temperature, no more than about 1
percent of the B factors of buried atoms is below 5.0. In liquid
nitrogen this percentage is allowed to be higher, of course.
 
Percentage of buried atoms with B less than 5 :   0.00
 
# 36 # Note: B-factor distribution normal
The distribution of B-factors within residues is within expected ranges.
A value over 1.5 here would mean that the B-factors show signs of
over-refinement.

# 40 # Note: Introduction to the nomenclature section.
Nomenclature problems seem, at first, rather unimportant. After all who
cares if we call the delta atoms in leucine delta2 and delta1 rather than
the other way around. Chemically speaking that is correct. But structures
have not been solved and deposited just for chemists to look at them. Most
times a structure is used, it is by software in a bioinformatics lab. And
if they compare structures in which the one used C delta1 and delta2 and the
other uses C delta2 and delta1, then that comparison will fail. Also, we
recalculate all structures every so many years to make sure that everybody
always can get access to the best coordinates that can be obtained from
the (your?) experimental data. These recalculations will be troublesome if
there are nomenclature problems.
 
Several nomenclature problems actually are worse than that. At the
WHAT CHECK website [REF] you can get an overview of the importance of all
nomenclature problems that we list.

(or this structure contains no nucleic acids).
 
# 51 # Note: Heavy atom naming OK
No errors were detected in the atom names for non-hydrogen atoms. Please
be aware that the PDB wants us to deliberately make some nomenclature errors;
especially in non-canonical amino acids.
 
# 52 # Note: No decreasing residue numbers
All residue numbers are strictly increasing within each chain.
 
# 53 # Note: All bond lengths OK
All bond lengths are in agreement with standard bond lengths using a
tolerance of 4 sigma (both standard values and sigma for amino acids
have been taken from Engh and Huber [REF], for DNA/RNA from Parkinson
et al [REF]).
 
# 54 # Warning: Low bond length variability
Bond lengths were found to deviate less than normal from the mean Engh and
Huber [REF] and/or Parkinson et al [REF] standard bond lengths. The RMS
Z-score given below is expected to be near 1.0 for a normally restrained
data set. The fact that it is lower than 0.667 in this structure might
indicate that too-strong restraints have been used in the refinement. This
can only be a problem  for high resolution X-ray structures.
 
 RMS Z-score for bond lengths: 0.398
 RMS-deviation in bond distances: 0.011
 
# 55 # Note: No bond length directionality
Comparison of bond distances with Engh and Huber [REF] standard values for
protein residues and Parkinson et al [REF] values for DNA/RNA does not show
significant systematic deviations.
 
# 56 # Warning: Unusual bond angles
The bond angles listed in the table below were found to deviate more than 4
sigma from standard bond angles (both standard values and sigma for protein
residues have been taken from Engh and Huber [REF], for DNA/RNA from
Parkinson et al [REF]). In the table below for each strange angle the bond
angle and the number of standard deviations it differs from the standard
values is given. Please note that disulphide bridges are neglected. Atoms
starting with "-" belong to the previous residue in the sequence.

angles (normal values for protein residues were taken from Engh and Huber
[REF], for DNA/RNA from Parkinson et al [REF]). The RMS Z-score given below
is expected to be near 1.0 for a normally restrained data set. The fact that
it is lower than 0.667 in this structure might indicate that too-strong

# 58 # Note: Residue hand check OK
No atoms are observed that have the wrong handedness. Be aware, though, that
WHAT CHECK might have corrected the handedness of some atoms already. The
handedness has not been corrected for any case where the problem is worse
than just an administrative discomfort.
 
# 59 # Note: Chirality OK
All protein atoms have proper chirality, or there is no intact protein
present in the PDB file.

# 61 # Note: Tau angles OK
All of the tau angles (N-C-alpha-C) of amino acids fall within expected
RMS deviations.
 
# 62 # Note: Normal tau angle deviations
The RMS Z-score for the tau angles (N-C-alpha-C) in the structure falls
within the normal range that we guess to be 0.5 - 1.5. Be aware, we
determined the tau normal distributions from 500 high-resolution X-ray
structures, rather than from CSD data, so we cannot be 100 percent certain
about these numbers.
 
 Tau angle RMS Z-score : 0.722
 
# 63 # Error: Side chain planarity problems
The side chains of the residues listed in the table below contain a planar
group that was found to deviate from planarity by more than 4.0 times the
expected value. For an amino acid residue that has a side chain with a
planar group, the RMS deviation of the atoms to a least squares plane was
determined. The number in the table is the number of standard deviations
this RMS value deviates from the expected value. Not knowing better yet, we
assume that planarity of the groups analyzed should be perfect.

# 64 # Note: Atoms connected to aromatic rings OK
All of the atoms that are connected to planar aromatic rings in side chains
of amino-acid residues are in the plane within expected RMS deviations.
Since there is no DNA and no protein with hydrogens, no uncalibrated
planarity check was performed.
 
# 65 # Note: Ramachandran Z-score OK
The score expressing how well the backbone conformations of all residues
correspond to the known allowed areas in the Ramachandran plot is within
expected ranges for well-refined structures.
 
 Ramachandran Z-score : -1.509
 
# 66 # Note: Ramachandran check
The list contains per-residue Z-scores describing how well each residue
fits into the allowed areas of the Ramachandran plot will not be printed
because WHAT CHECK found no reason to cry.
 
# 67 # Warning: Torsion angle evaluation shows unusual residues
The residues listed in the table below contain bad or abnormal
torsion angles.
 
These scores give an impression of how `normal' the torsion angles in
protein residues are. All torsion angles except omega are used for
calculating a `normality' score. Average values and standard deviations were
obtained from the residues in the WHAT CHECK database. These are used to
calculate Z-scores. A residue with a Z-score of below -2.0 is poor, and a
score of less than -3.0 is worrying. For such residues more than one torsion

# 71 # Warning: Unusual rotamers
The residues listed in the table below have a rotamer that is not seen very
often in the database of solved protein structures. This option determines
for every residue the position specific chi-1 rotamer distribution.
Thereafter it verified whether the actual residue in the molecule has the
most preferred rotamer or not. If the actual rotamer is the preferred one,
the score is 1.0. If the actual rotamer is unique, the score is 0.0. If
there are two preferred rotamers, with a population distribution of 3:2 and
your rotamer sits in the lesser populated rotamer, the score will be 0.667.
No value will be given if insufficient hits are found in the database.
 
It is not necessarily an error if a few residues have rotamer values below
0.3, but careful inspection of all residues with these low values could be
worth it.

# 72 # Warning: Unusual backbone conformations
For the residues listed in the table below, the backbone formed by itself and
two neighbouring residues on either side is in a conformation that is not
seen very often in the database of solved protein structures. The number
given in the table is the number of similar backbone conformations in the
database with the same amino acid in the centre.
 
For this check, backbone conformations are compared with database structures
using C-alpha superpositions with some restraints on the backbone oxygen
positions.
 
A residue mentioned in the table can be part of a strange loop, or there
might be something wrong with it or its directly surrounding residues. There
are a few of these in every protein, but in any case it is worth looking at,
especially if a regular DSSP secondary structure (H or S for helix or strand,
respectively) is indicated!

# 75 # Warning: Unusual PRO puckering amplitudes
The proline residues listed in the table below have a puckering amplitude
that is outside of normal ranges. Puckering parameters were calculated by
the method of Cremer and Pople [REF]. Normal PRO rings have a puckering
amplitude Q between 0.20 and 0.45 Angstrom. If Q is lower than 0.20 Angstrom
for a PRO residue, this could indicate disorder between the two different
normal ring forms (with C-gamma below and above the ring, respectively). If
Q is higher than 0.45 Angstrom something could have gone wrong during the
refinement. Be aware that this is a warning with a low confidence level. See:

resolution structures [REF]

# 76 # Warning: Unusual PRO puckering phases
The proline residues listed in the table below have a puckering phase that is
not expected to occur in protein structures. Puckering parameters were
calculated by the method of Cremer and Pople [REF]. Normal PRO rings
approximately show a so-called envelope conformation with the C-gamma atom
above the plane of the ring (phi=+72 degrees), or a half-chair conformation
with C-gamma below and C-beta above the plane of the ring (phi=-90 degrees).
If phi deviates strongly from these values, this is indicative of a very
strange conformation for a PRO residue, and definitely requires a manual
check of the data. Be aware that this is a warning with a low confidence
level. See: Who checks the checkers? Four validation tools applied to eight
atomic resolution structures [REF].

# 77 # Warning: Backbone oxygen evaluation
The residues listed in the table below have an unusual backbone oxygen
position.
 
For each of the residues in the structure, a search was performed to find
5-residue stretches in the WHAT CHECK database with superposable C-alpha
coordinates, and some restraints on the neighbouring backbone oxygens.
 
In the following table the RMS distance between the backbone oxygen positions
of these matching structures in the database and the position of the backbone
oxygen atom in the current residue is given. If this number is larger than
1.5 a significant number of structures in the database show an alternative
position for the backbone oxygen. If the number is larger than 2.0 most
matching backbone fragments in the database have the peptide plane flipped.
A manual check needs to be performed to assess whether the experimental data
can support that alternative as well. The number in the last column is the
number of database hits (maximum 80) used in the calculation. It is "normal"
that some glycine residues show up in this list, but they are still worth
checking!

# 78 # Warning: Possible peptide flips
For the residues listed in the table below, the backbone formed by the
residue mentioned and the one N-terminal of it show systematic deviations
from normality that are consistent with a peptide flip. This can either
be a 180 degree flip of the entire peptide plane or a trans to cis flip.
(Cis to trans flips cannot be detected yet). The type can be TT+, TC-,
or TC+:
TT+ indicates a 180 degree flip of the entire peptide plane.
TC- indicates a trans to cis conversion that requires a flip of the N atom.
TC+ indicates a trans to cis conversion that requires a flip of the O atom.
Note that the method will only work correctly for PDB files with full
isotropic B-factors.

# 79 # Error: Abnormally short interatomic distances
The pairs of atoms listed in the table below have an unusually short
interactomic distance; each bump is listed in only one direction.
 
The contact distances of all atom pairs have been checked. Two atoms are
said to `bump' if they are closer than the sum of their Van der Waals radii
minus 0.40 Angstrom. For hydrogen bonded pairs a tolerance of 0.55 Angstrom
is used. The first number in the table tells you how much shorter that
specific contact is than the acceptable limit. The second distance is the
distance between the centres of the two atoms. Although we believe that two
water atoms at 2.4 A distance are too close, we only report water pairs that
are closer than this rather short distance.
 
INTRA and INTER indicate whether the clashes are between atoms in the same
asymmetric unit, or atoms in symmetry related asymmetric units, respectively.
The last text-item on each line represents the status of the atom pair. If
the final column contains the text 'HB', the bump criterion was relaxed
because there could be a hydrogen bond. Similarly relaxed criteria are used
for 1--3 and 1--4 interactions (listed as 'B2' and 'B3', respectively).
If the last column is 'BF', the sum of the B-factors of the atoms is higher
than 80, which makes the appearance of the bump somewhat less severe because
the atoms probably are not there anyway. BL, on the other hand, indicates
that the bumping atoms both have a low B-factor, and that makes the bumps
more worrisome.
 
Bumps between atoms for which the sum of their occupancies is lower than one
are not reported. If the MODEL number does not exist (as is the case in most
X-ray files), a minus sign is printed instead.

The residues listed in the table below have an unusual packing environment.
 
The packing environment of the residues is compared with the average packing
environment for all residues of the same type in good PDB files. A low
packing score can indicate one of several things: Poor packing, misthreading
of the sequence through the density, crystal contacts, contacts with a
co-factor, or the residue is part of the active site. It is not uncommon to
see a few of these, but in any case this requires further inspection of the
residue.

For all complete HIS residues in the structure a tentative assignment to
HIS-D (protonated on ND1), HIS-E (protonated on NE2), or HIS-H (protonated
on both ND1 and NE2, positively charged) is made based on the hydrogen bond
network. A second assignment is made based on which of the Engh and Huber
[REF] histidine geometries fits best to the structure.
 
In the table below all normal histidine residues are listed. The assignment
based on the geometry of the residue is listed first, together with the RMS
Z-score for the fit to the Engh and Huber parameters. For all residues where
the H-bond assignment is different, the assignment is listed in the last
columns, together with its RMS Z-score to the Engh and Huber parameters.
 
As always, the RMS Z-scores should be close to 1.0 if the residues were
restrained to the Engh and Huber parameters during refinement, and if
enough (high resolution) data is available.
 
Please note that because the differences between the geometries of the
different types are small it is possible that the geometric assignment given
here does not correspond to the type used in refinement. This is especially
true if the RMS Z-scores are much higher than 1.0.
 
If the two assignments differ, or the `geometry' RMS Z-score is high, it is
advisable to verify the hydrogen bond assignment, check the HIS type used
during the refinement and possibly adjust it.

# 100 # Warning: Buried unsatisfied hydrogen bond donors
The buried hydrogen bond donors listed in the table below have a hydrogen
atom that is not involved in a hydrogen bond in the optimized hydrogen bond
network.
 
Hydrogen bond donors that are buried inside the protein normally use all of
their hydrogens to form hydrogen bonds within the protein. If there are any
non hydrogen bonded buried hydrogen bond donors in the structure they will
be listed here. In very good structures the number of listed atoms will tend
to zero.
 
Waters are not listed by this option.

# 101 # Warning: Buried unsatisfied hydrogen bond acceptors
The buried side-chain hydrogen bond acceptors listed in the table below are
not involved in a hydrogen bond in the optimized hydrogen bond network.
 
Side-chain hydrogen bond acceptors buried inside the protein normally form
hydrogen bonds within the protein. If there are any not hydrogen bonded in
the optimized hydrogen bond network they will be listed here.

# 102 # Note: Some notes regarding these donors and acceptors
The donors and acceptors have been counted, also as function of their
accessibility. The buried donors and acceptors have been binned in five
categories ranging from not forming any hydrogen bond till forming a poor
till perfect hydrogen bond. Obviously, the buried donors and acceptors
with no or just a poor hydrogen bond should be a topic of concern. As every
protein contains more acceptors than donors, unsatisfied donors are more in
need of attention than unsatisfied acceptors.

# 104 # Note: Summary report
This is an overall summary of the quality of the structure as compared with
current reliable structures. Numbers in brackets are the average and standard
deviation observed for a large number of files determined with a similar
resolution.
 
The second table mostly gives an impression of how well the model conforms
to common refinement restraint values. These numbers are less than 1.0 if the
spread in data is too little, and larger than 1.0 when the spread is too
large. The former does not need to be a problem, the latter always is bad.
 
 Structure Z-scores, positive is better than average:
  Resolution read from PDB file  :   2.510
  1st generation packing quality :   0.056 (          (  -0.5,  2.5))
  2nd generation packing quality :   0.403 (          (  -1.5,  1.2))
  Ramachandran plot appearance   :  -1.509 (          (  -2.7,  1.6))
  chi-1/chi-2 rotamer normality  :  -3.423 (poor      (  -4.5,  1.7))
  Backbone conformation          :   0.220 (          (  -0.8,  3.7))
  Inside/Outside distribution    :   1.003
 
 RMS Z-scores, should be close to 1.0:
  Bond lengths                   :   0.398 (tight)
  Bond angles                    :   0.609 (tight)
  Omega angle restraints         :   1.141
  Side chain planarity           :   0.827
  Improper dihedral distribution :   0.500
  B-factor distribution          :   0.567
 
# 105 # Note: Introduction to refinement recommendations
First, be aware that the recommendations for crystallographers listed below
are produced by a computer program that was written by a guy who got his
PhD in NMR...
 
We have tried to convert the messages written in this report into a small
set of things you can do with your refinement software to get a better
structure. The things you should do first are listed first. And in some
cases you should first fix that problem, then refine a bit further, and
then run WHAT CHECK again before looking at other problems. If, for example,
WHAT CHECK has found a problem with the SCALE and CRYST cards, then you must
first fix that problem, refine the structure a bit further, and run WHAT
CHECK again because errors in the SCALE and or CRYST card can lead to many
problems elsewhere in the validation process.
 
It is also important to keep in mind that WHAT CHECK is software and that it
occasionally totally misunderstands what is the cause of a problem. But, if
WHAT CHECK lists a problem there normally is a problem albeit that it not
always is the actual problem that gets listed.
 
# 106 # Note: Matthews coefficient problem
WHAT CHECK detected a Matthews coefficient problem. Most times this is an
administrative problem caused by typing the wrong cell multiplicity number
on the CRYST card (or not typing it at all). Occasionally it is caused by
typing the wrong space group on the CRYST card. You better fix this problem,
but normally this problem does not cause WHAT CHECK to give any erroneous
error messages further down in the report.
 
# 107 # Error: Bumps in your structure
Upon analysing the bumps in your structure, WHAT CHECK got a bit
worried. Sometimes this means that you have forgotten to lower the
occupancy of overlapping ligands, residues, or water molecules. But,
whatever is the origin of this problem, you have to analyse it and
fix it.
 
# 108 # Note: His, Asn, Gln side chain flips.
His, Asn, and Gln have an asymmetry in their side chain that is hard to
detect unless you have data at much better than 1.0 Angstrom resolution.
WHAT CHECK thinks that your structure contains His, Asn, or Gln residues that
will make better hydrogen bonds when flipped around their chi-2, chi-2, or
chi-3 side chain torsion angle, respectively. You better
check these Asn, His, and Gln residues, and if you use a refinement program
that includes molecular dynamics, then you must (after the
flips were made) refine a bit further before running WHAT CHECK again.
 
# 109 # Warning: Troublesome residues
The residues listed in the table below need to be inspected
 
This table is a very rough attempt to sort the residues according to how
badly they need your attention. The idea is that when you sit in  in front
of the graphics screen and study the residues with the electron density
present that you improve the structure most by dealing with the top residues
in this list first.
