Peptidyl-dipeptidase DCP (IPR034005)

Short name: M3A_DCP

Overlapping homologous superfamilies

Family relationships



This entry includes the following members of peptidase subfamily M3A: peptidyl dipeptidase DCP (EC; MEROPS identifier M03.005; also known as dipeptidyl carboxypeptidase) and oligopeptidase A (OpdA; EC; MEROPS identifier M03.004). DCP releases dipeptides from the C-termini of various peptides and proteins, the smallest substrate being N-blocked tripeptides and unblocked tetrapeptides. DCP from E. coli is inhibited by the anti-hypertensive drug captopril, an inhibitor of the mammalian angiotensin converting enzyme (ACE, also called peptidyl dipeptidase A) [PMID: 19558329, PMID: 15876371]. Oligopeptidase A (OpdA) may play a specific role in the degradation of signal peptides after they are released from precursor forms of secreted proteins. It can also cleave N-acetyl-L-Ala [PMID: 7674945].
