Dipeptidyl peptidase (DPP) is an enzyme which cleaves dipeptides from plolypeptides. DPP-IV (or CD26) cleaves proline dipeptides from the N-termini and is associated with immune regulation. DPP-III acts similarly to DPP-IV. DPP-I is involved in inflammatory diseases. DPP-II is a serine protease. The images at the left and at the right correspond to one representative DPP, i.e. the crystal structure of Dipeptidyl peptidase-I from rat (1jqp).
