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, in sequential ascending order, without reference to the name of the molecule. | For many years, depositors of models could request an available PDB code that represented an acronym for the molecule represented.

==PDB codes are permanently associated with a single structure== | |||
Once a PDB id is assigned to a given structure, it's forever, even in those cases when a structure is withdrawn (retired from the database), like [[3luw]] or superseded by a newer or corrected structure, like [[1ace]]. | |||
