Leukocitna elastaza (EC 3.4.21.37, lizozomalna elastaza, neutrofilna elastaza, polimorfonuklearna leukocitna elastaza, elastaza, elaszim, serinska elastaza, lizozomalna elastaza, granulocitna elastaza) je enzim.[1][2][3][4] Ovaj enzim katalizuje sledeću hemijsku reakciju
- Hidroliza proteina, uključujući elastin. Preferentno odvajanje Val- > Ala-
Ovaj enzim se razlikuje od pankreasne elastaze po specifičnosti na sintetičim supstratima i po senzitivnosti na inhibitore.
