THE PDBFINDER DATABASE - A SUMMARY OF PDB, DSSP AND HSSP INFORMATION WITH ADDED VALUE

Motivation: The Protein Data Bank currently contains more than 4700 pr otein coordinate sets. It is often desirable to make a selection from these files based on a criterion like R-factor, experimental method, l ength of the amino acid sequence, or the number of homologous sequence s in SWISSPROT. Doing this using the distributed form of the Protein D ata Bank can be a tedious task, because (I) this requires reading one file for every single entry, and (2) not all of the information is pre sent in a consistent computer readable way in all of the entries. Resu lts: The PDBFINDER database provides an easy to interpret file contain ing summary information about all Protein Data Bank files. Summary inf ormation from the DSSP (Definition of Secondary Structure of Proteins) and HSSP (Homology derived Secondary Structure of Proteins) databases is also included. Furthermore, where essential data were missing from the Protein Data Bank file, this information has been retrieved from the original literature.
