PDBx:entity_keywordsType 

Data items in the ENTITY_KEYWORDS category specify keywords
relevant to the molecular entities. Note that this list of
keywords is separate from the list that is used for the
STRUCT_BIOL data items and is intended to provide only the
information that one would know about the molecular entity *if
one did not know its structure*. Hence polypeptides are simply
polypeptides, not cytokines or beta-alpha-barrels, and
polyribonucleic acids are simply poly-RNA, not transfer-
RNA.

    Example 1 - based on PDB entry 5HVP and laboratory records for the
                structure corresponding to PDB entry 5HVP.
