Tripeptide aminopeptidase (EC 3.4.11.4, tripeptidase, aminotripeptidase, aminoexotripeptidase, lymphopeptidase, imidoendopeptidase, peptidase B, alanine-phenylalanine-proline arylamidase, peptidase T) is an enzyme.[1][2] This enzyme catalyses the following chemical reaction:

Release of the N-terminal residue from a tripeptide

This is a zinc enzyme, widely distributed in mammalian tissues.
