REMARK 1

REMARK 1 lists important publications related to the structure presented in the entry. These citations are chosen by the depositor. They are listed in reverse-chronological order. Citations are not repeated from the JRNL records. After the first blank record and the REFERENCE sub-record, the sub-record types for REMARK 1 are the same as in the JRNL sub-record types. For details, see the JRNL section.

Record Format and Details

As with all other remarks, the first line is empty and is used as a spacer.

The following tables are used to describe the sub-record types of REMARK 1.

1. REFERENCE

Each reference is preceded by a line indicating the reference number in the entry.

5. REF

REF is a group of fields which contains the name of the publication.

5a. If it has not been published yet, the REF sub-record type has the form:

COLUMNS     DATA TYPE       FIELD                DEFINITION
-----------------------------------------------------------
 1 -  6     Record name     "REMARK"

13 - 16     LString(3)      "REF"
20 - 34     LString(15)     "TO BE PUBLISHED"

At the present time, there is no formal mechanism in place for monitoring the subsequent publication of referenced papers. PDB relies upon the depositor to provide reference update information since preliminary information can change by the time of actual publication.

5b. If the reference has been published, then the REF sub-record type group contains information about the name of the publication, supplement, report, volume, page, and year, in the appropriate fields.

REMARK 2

REMARK 2 states the highest resolution, in Angstroms, that was used in building the model. As with all the remarks, the first REMARK 2 record is empty and is used as a spacer.

Record Format and Details

  • The second REMARK 2 record has one of two formats. The first is used for diffraction studies, the second for other types of experiments in which resolution is not relevant, e.g., NMR and theoretical modeling.
  • For diffraction experiments:

    REMARK 4-999

    Overview

    REMARKs following the refinement remark consist of free text annotation, predefined boilerplate remarks, and token: value pair styled templates. Presented here are examples of remark sections in PDB files

    Record Format and Details

  • Non-standard remark annotations, or those with no clearly-defined topic or assigned remark number, appear with remark number 6 or greater, but less than remark number 100.
  • Note that A, B, N, X, Y, and Z are used to represent variables in the following examples.
  • As with all other remarks, the first line of each remark is empty and is used as a spacer.

  • REMARK 4

    Remark 4 indicates the version of the PDB file format used to generate the file.
