Additional subtopics may be added as needed. For close contacts, the cutoff limit is 2.2 Angstroms for non-hydrogen atoms and is 1.6 Angstroms for H and D atoms. These distances are listed in the REMARK 500 for close contacts symmetry.
All the calculations on RMSD deviations include all the atoms present in the coordinates including atoms with zero occupancy.
The calculation of bond and angle deviations for protein entries will be based on the updated Engh & Huber amino acid target values1. For nucleic acids, the Parkinson et al., statistics will be used for these calculations2. All bonds and angles that deviate more than 6 times from their standard target values will be flagged as a deviation. The PHI/PSI values are based on the Kleywegt-Jones calculations3.
The improper CA-C-CB-N angles for chiral centers are calculated and are defined below with 10 degree allowed deviations.
+35 for L amino acids
-35 for D amino acids
- +25 to +45 degree range is defined as sp3, L.
If D is expected, it gives "WRONG HAND" in the details. If the calculated value is positive and outside this range, it gives "OUTSIDE RANGE" in the details. - -10 to +10 degree range is defined as sp2, planar.
If it is expected to be sp2 and the value is outside this range, it gives "EXPECTING PLANAR" in the details. If it is expected to be sp3 and the value is within this range, it gives "EXPECTING SP3" in the details. - -45 to -25 degree range is defined as sp3, D.
If L is expected, it gives "WRONG HAND" in the details. If the calculated value is negative and outside this range, it gives "OUTSIDE RANGE" in the details.
The improper CA-C-CB-N angles for chiral centers are calculated for all the alternate conformations. However alt id will not be listed for outliers where residue involves alternate conformations.

Ligands or hetgroups that are not part of any polymer (protein or nucleic acid) in the structure may also have missing atoms or atoms with zero occupancy. In such instances the name of the hetgroup or ligand, chain ID and model number (if applicable) will be listed in REMARK 610 (for missing atoms) or REMARK 615 (for atoms with 0.00 occupancy). As the list of specific atoms missing from a hetgroup may be really large, they will not listed in the remarks described above. The list of all missing atoms from the ligands may be easily derived by comparing the coordinates of the hetgroup to its definition in the ligand dictionary.

REMARK 700 REMARK 700 SHEET REMARK 700 STRANDS 1 TO 4 OF THE BETA-SHEET HAVE GREEK-KEY TOPOLOGY. REMARK 700 THE SHEET FORMS A FIVE-STRANDED BETA-BARREL WITH BULGES IN REMARK 700 STRANDS 3 AND 5. IN ORDER TO REPRESENT THIS FEATURE IN THE REMARK 700 SHEET RECORDS BELOW, TWO SHEETS ARE DEFINED. REMARK 700 REMARK 700 SHEET REMARK 700 THE SHEET PRESENTED AS S5 ON SHEET RECORDS BELOW IS REMARK 700 ACTUALLY A 6-STRANDED BETA-BARREL. THIS IS REMARK 700 REPRESENTED BY A 7-STRANDED SHEET IN WHICH THE FIRST AND REMARK 700 LAST STRANDS ARE IDENTICAL. REMARK 700 REMARK 700 SHEET REMARK 700 DETERMINATION METHOD: AUTHOR PROVIDED.

REMARK 999, Sequence
This remark is a free text remark which describes anything unusual about a particular polymer sequence in SEQRES records.
For examples,
- If the exact sequence of the sample is not known, due to, for example, proteolysis, the sequence should match the coordinates and a REMARK 999 can be added.
- The information about a sequence region of a chimeric protein which does not match the UNP entry, such as a linker region, can be added to REMARK 999.
- Sequence conflicts which are listed in the UNP reference can also be described in REMARK 999. A full explanation of the microheterogeneity for all residues at a particular residue number can be elaborated in REMARK 999.
- If the coordinates alignment with the sequence is unknown and the residue numbering is arbitrary. The sequence would be poly UNK. The sequence, if it is known, would be listed in the REMARK 999
