Overview
This record gives the chemical name of the compound with the given hetID.
Record Format
COLUMNS DATA TYPE FIELD DEFINITION
-------------------------------------------------------------------------
1 - 6 Record name "HETNAM"
9 - 10 Continuation continuation Allows concatenation of
multiple records.
12 - 14 LString(3) hetID Het identifier,
right-justified.
16 - 70 String text Chemical name.
Details
* Each hetID is assigned a unique chemical name for the HETNAM record.
* Other names for the group are given on HETSYN records.
* PDB follows IUPAC/IUB naming conventions to describe groups systematically.
* Continuation of chemical names onto subsequent records is allowed.
* Only one HETNAM record is included for a given hetID, even if the same hetID appears on more than one HET record.
Verification/Validation/Value Authority Control
For each het group that appears in the entry, the corresponding HET, HETNAM, FORMUL, HETATM and CONECT records must appear. The HETNAM record is generated automatically by PDB using the het group dictionary and information from HETATM records.
Relationships to Other Record Types
For each het group that appears in the entry, the corresponding HET, HETNAM, FORMUL, HETATM, and CONECT records must appear. HETSYN and LINK records may also appear.
