BDB: databank of PDB files with consistent B-factors.

Protein structures available from the PDB contain for each atom the coordinates, the occupancy and the B-factor that indicates the mobility of the atom. The values that should represent B-factors can relate to atomic motions in different ways. We present here a databank in which all B-factors have been converted to the one, homogeneous representation that is most useful for protein engineering applications. The Databank of PDB files with consistent B-factors (BDB) is freely available through http://www.cmbi.umcn.nl/bdb/.
