Category Description

               Data items in the STRUCT_SITE category record details about
               portions of the structure that contribute to structurally
               relevant sites (e.g. active sites, substrate-binding subsites,
               metal-coordination sites).

Additional Descriptive Information for Depositors

 Ligand binding sites. Ligand binding site records are used to annotate the binding environment of any non-polymeric heterogen.  SITE records will define any interacting residues, based on a distance cutoff from a ligand. They can be generated by the author and/or by software and an evidence code (_struct_site.pdbx_evidence_code)  has been added to identify whether the SITE records is software calculated or author provided.

Category Example

    ; residues with a contact < 3.7 \%A to an atom in the P2
      moiety of the inhibitor in the conformation with
      _struct_asym.id = C
    ;
     'P2 site D'
    ; residues with a contact < 3.7 \%A to an atom in the P1
      moiety of the inhibitor in the conformation with
      _struct_asym.id = D)
