Category Description

               Data items in the ATOM_SITE category record details about
               the atom sites in a macromolecular crystal structure, such as
               the positional coordinates, atomic displacement parameters,
               magnetic moments and directions.

               The data items for describing anisotropic atomic
               displacement factors are only used if the corresponding items
               are not given in the ATOM_SITE_ANISOTROP category.

               wwPDB recommends wwPDB-assigned residue number, residue ID,
               and chain ID, _atom_site.auth_seq_id _atom_site.auth_comp_id, and
               _atom_site.auth_asym_id, respectively, to be used for publication
	       materials.
