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. | For many years, depositors of models could request an available PDB code that represented an acronym for the molecule represented.

There are over 400,000 possible 4-character PDB identification codes (419,904 or 466,560 if "0" is allowed as the first character). Thus, the ~ | There are over 400,000 possible 4-character PDB identification codes (419,904 or 466,560 if "0" is allowed as the first character). Thus, the ~78,000 entries in early 2012 have used up less than 19% of the available codes. Someday a scheme that can accomodate more entries will be required, requiring revision of macromolecular visualization and modeling software programs that obtain data online, all of which, of necessity, currently require 4-character PDB codes. | ||
