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 ~89,000 entries in early 2013 have used up ~21% 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. | ||
