 Protein Data Bank file format is a most popular format for holding biomolecule data.
 
-This is a very fast parser: below 7s for the largest entry in PDB - 1HTQ which is over 70MB - as compared with 11s of RASMOL 2.7.5, or 2m15s of BioPython with Python 2.6 interpreter.

 It is aimed to not only deliver event-based interface, but also a high-level data structure for manipulating data in spirit of BioPython's PDB parser.
