    _item_description.description
;              The group of atoms to which the _atom_site. belongs.
                 ATOM -- an atom site for a "standard" residue
                 HETA -- an atom site for a "non-standard" residue
                   (alternatively "HETATM")
                 TER  -- a dummy atom site marking the termination
                   of a chain
                 For a protein the residue of a TER record is the
                 carboxy-terminal residue.  For a nuclei acid it is
                 the 3'-terminal residue.
