Appendix 1: Accession numbers
MMDB records have several types of Accession numbers associated with them,
representing the following data types:
x Each MMDB record has at least three Accession numbers: the PDB code of the
corresponding PDB record (e.g., 1CYO, 1B8G); a unique MMDB-ID (e.g., 645,
12342); and a gi number for each protein chain. A new MMDB-ID is assigned
whenever PDB updates either the sequence or coordinates of a structure record,
even if the PDB code is retained.
x If an MMDB record contains more than one polypeptide or nucleotide chain, each
chain in the MMDB record is assigned an Accession number in Entrez Protein or
