* HEADER [#dd8f1d67]
** Overview [#v2fa8f56]
The HEADER record uniquely identifies a PDB entry through the idCode field. This record also provides a classification for the entry. Finally, it contains the date the coordinates were deposited at the PDB.
** Record Format [#m477c34a]
COLUMNS DATA TYPE FIELD DEFINITION
---------------------------------------------------------------------------
1 - 6 Record name "HEADER"
11 - 50 String(40) classification Classifies the molecule(s)
51 - 59 Date depDate Deposition date.
This is the date the coordinates were
received by the PDB
63 - 66 IDcode idCode This identifier is unique within the PDB
** Details [#r783bd6f]
The classification string is left-justified and exactly matches one of a collection of strings. See the class list available from the WWW site. In the case of macromolecular complexes, the classification field must present a class for each macromolecule present. Due to the limited length of the classification field, strings must sometimes be abbreviated. In these cases, the full terms are given in KEYWDS.~
Classification may be based on function, metabolic role, molecule type, cellular location, etc. In the case of a molecule having a dual function, both may be presented here.
** Verification/Validation/Value Authority Control [#j779aac8]
The verification program checks that the deposition date is a legitimate date and that the ID code is well-formed.
#br
PDB coordinate entry ID codes do not begin with 0, as this is used to identify the NOC ("no coordinates) files that are bibliographic only, not structural entries.
Relationships to Other Record Types
#br
The classification found in HEADER also appears in KEYWDS, unabbreviated and in no strict order.
