Dipeptidyl peptidase IV and process for producing the same

摘要

Dipeptidyl peptidase IV obtainable from a microorganism of the genus Xanthomonas is described, which hydrolyzes specifically a peptide and derivatives thereof having proline at the second position from the amino terminus to release a dipeptide having proline at the carboxyl terminus. Also, the process for producing the dipeptidyl peptidase IV is described.
