Accepted name: dipeptidyl-peptidase III
Reaction: Release of an N-terminal dipeptide from a peptide comprising four or more residues, with broad specificity. Also acts on dipeptidyl 2-naphthylamides.
Other name(s): dipeptidyl aminopeptidase III; dipeptidyl arylamidase III; enkephalinase B; red cell angiotensinase
Comments: A cytosolic peptidase that is active at neutral pH. It has broad activity on peptides, although it is highly selective for Arg-Arg-2-naphthylamide, at pH 9.2. Active in the hydrolysis of enkephalins. A metallopeptidase, the type example of peptidase family M49.
