Regardless of the chain IDs assigned by the authors of a structure model entry deposited in the wwPDB, the wwPDB assigns its own (usually distinct) chain IDs. These PDBx chain IDs are present only in the mmCIF files, not in the PDB format files. In mmCIF files, there is no single place that lists all author-assigned or all wwPDB-assigned chain IDs. | Regardless of the chain IDs assigned by the authors of a structure model entry deposited in the wwPDB, the wwPDB assigns its own (usually distinct) chain IDs.
