Tripeptidilna peptidaza I (EC 3.4.14.9, tripeptidilna aminopeptidaza, tripeptidilna peptidaza) je enzim.[1][2][3][4][5] Ovaj enzim katalizuje sledeću hemijsku reakciju
- Odvajanje N-terminalnog tripeptida sa polipeptida. Takođe deluje kao endopeptidaza.
Ovaj lizozomalni enzim je aktivan pri kiselom pH.
