XmlmmCIF equivalent: struct_ref_seq_dif Data items in the STRUCT_REF_SEQ_DIF category provide a mechanism for indicating and annotating point differences between the sequence of the entity or biological unit described in the data block and the sequence of the referenced database entry. XmlmmCIF equivalent: struct_ref_seq_dif/db_mon_id The monomer type found at this position in the referenced database entry. This data item is a pointer to _chem_comp.id in the CHEM_COMP category. XmlmmCIF equivalent: struct_ref_seq_dif/details A description of special aspects of the point differences between the sequence of the entity or biological unit described in the data block and the referenced database entry. XmlmmCIF equivalent: struct_ref_seq_dif/mon_id The monomer type found at this position in the sequence of the entity or biological unit described in this data block. This data item is a pointer to _chem_comp.id in the CHEM_COMP category. XmlmmCIF equivalent: struct_ref_seq_dif/pdbx_auth_seq_num Insertion code in PDB sequence XmlmmCIF equivalent: struct_ref_seq_dif/pdbx_pdb_id_code The PDB ID code. XmlmmCIF equivalent: struct_ref_seq_dif/pdbx_pdb_ins_code Insertion code in PDB sequence XmlmmCIF equivalent: struct_ref_seq_dif/pdbx_pdb_strand_id PDB strand/chain id. XmlmmCIF equivalent: struct_ref_seq_dif/pdbx_seq_db_accession_code Sequence database accession number. XmlmmCIF equivalent: struct_ref_seq_dif/pdbx_seq_db_name Sequence database name. XmlmmCIF equivalent: struct_ref_seq_dif/pdbx_seq_db_seq_num Sequence database sequence number. XmlmmCIF equivalent: struct_ref_seq_dif/align_id This data item is a pointer to _struct_ref_seq.align_id in the STRUCT_REF_SEQ category. XmlmmCIF equivalent: struct_ref_seq_dif/seq_num This data item is a pointer to _entity_poly_seq.num in the ENTITY_POLY_SEQ category.
