Every molecular model (atomic coordinate file) in the Protein Data Bank (PDB) has a unique accession or identification code. These codes are always 4 characters in length. The first character is a numeral, while the last three characters can be either numerals or letters. In the past, the first character was always a numeral in the range 1-9. Although there appear to be no entries beginning with <q>0</q>, its exclusion may have been relaxed.
Every released entry in the PDB has an automatically-generated page in Proteopedia. Proteopedia is updated once each week, shortly following the weekly new release cycle at the PDB.
Examples:
- 1mbn a 1973 model of myoglobin, the first protein structure solved.
- 1tna a 1975 model of yeast phenylalanine transfer RNA, the first RNA structure solved.
- 2hhd human hemoglobin, deoxy.
For many years, depositors of models could request an available PDB code that represented an acronym for the molecule represented. 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.
