Dipeptidyl-peptidase II (EC 3.4.14.2, dipeptidyl aminopeptidase II, dipeptidyl arylamidase II, carboxytripeptidase, dipeptidyl peptidase II, DAP II, dipeptidyl(amino)peptidase II, dipeptidylarylamidase) is an enzyme.[1][2] This enzyme catalyses the following chemical reaction
- Release of an N-terminal dipeptide, Xaa-Yaa!, preferentially when Yaa is Ala or Pro. Substrates are oligopeptides, preferentially tripeptides
This lysosomal serine-type peptidase is maximally active at acidic pH.
