CIF APPLICATIONS - VIII - PDB2CIF - TRANSLATING PDB ENTRIES INTO MMCIF FORMAT

pdb2cif is a new version of an awk script originally written by P. E. Bourne in 1993 to translate from the 1992 Protein Data Bank (PDB) form at to the then-emerging macromolecular Crystallographic Information Fi le (mmCIF) definition. This new version of pdb2cif translates from all current PDB formats, including the 1992 PDB format and the 1996 PDB A tomic Coordinate Entry Format, Version 2.0, to the 1997 mmCIF format a s defined in the mmCIF dictionary 1.0.00. The program is provided as a n m4 script from which both perl and awk versions can be produced. The program identifies mmCIF entities implicitly by sequence homology amo ng PDB SEQRES records. With minor additions to the dictionary, the res ultant mmCIF data-sets are substantially compliant with the mmCIF 1.0. 00 dictionary.
