Accepted name: peptidyl-dipeptidase Dcp
Reaction: Hydrolysis of unblocked, C-terminal dipeptides from oligopeptides, with broad specificity. Does not hydrolyse bonds in which P1′ is Pro, or both P1 and P1′ are Gly
Other name(s): dipeptidyl carboxypeptidase (Dcp); dipeptidyl carboxypeptidase
Comments: Known from Escherichia coli and Salmonella typhimurium. A zinc metallopeptidase in peptidase family M3 (thimet oligopeptidase family). Ac-Ala┼Ala-Ala is a good test substrate [3]. Inhibited by captopril, as is peptidyl-dipeptidase A. Formerly EC, and included in EC, peptidyl-dipeptidase A.
