RAT SPECIFIC CATHEPSIN, DIPEPTIDYL PEPTIDASE I (DPPI): CRYSTAL STRUCTURE, INGREDIENTS AND ITS APPLICATIONS

摘要

The present invention relates to structural studies of dipeptidyl peptidase I (DPPI) proteins, modified dipeptidyl peptidase I (DPPI) proteins and DPPI co-complexes. Included in the present invention is a crystal of a dipeptidyl peptidase I (DPPI) and corresponding structural information obtained by X-ray crystallography from rat and human DPPI. In addition, this invention relates to methods for using structure co-ordinates of DDPI, mutants hereof andco-complexes, to design compounds that bind to the active site or accessory binding sites of DPPI and to design improved inhibitors of DPPI or homologues of the enzyme.
