Category ENTITY_POLY_SEQ

Name:
'entity_poly_seq'

Description:

   Data items in the ENTITY_POLY_SEQ category specify the sequence
   of monomers in a polymer. Allowance is made for the possibility
   of microheterogeneity in a sample by allowing a given sequence
   number to be correlated with more than one monomer ID. The
   corresponding ATOM_SITE entries should reflect this
   heterogeneity.

Example:

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