Monomeric ligands and other non-polymers that are assigned the chain name of the associated polymer are always assigned the author-assigned polymer IDs, when the model is compatible with the PDB format -- and hence always get single-character names.

When the entry is not compatible with PDB format, for example it has >62 chains, some author-assigned chain names will have at least two characters.

wwPDB-assigned chain IDs are all '''upper case letters''', and follow this sequence: A-Z, AA-ZA, BA-ZA, ... AZ-ZZ, AAA-ZAA, ABA-ZBA, etc.
