==Newer PDB Codes are Random==
==Newer PDB Codes are Sequential==


For many years, depositors of models could request an available PDB code that represented an acronym for the molecule represented. All the above examples are such cases. With the increase in number of new entries each week, the PDB no longer permits this option. In recent years, all PDB codes are assigned by the PDB from the pool of available codes, without reference to the name of the molecule.

With the increase in number of new entries each week, the PDB no longer permits this option. In recent years, all PDB codes are assigned by the PDB from the pool of available codes, in sequential ascending order, without reference to the name of the molecule.
