Arahidonat 5-lipoksigenaza (EC 1.13.11.34, leukotrien-A4 sintaza, Delta5-lipoksigenaza, 5Delta-lipoksigenaza, arahidonska 5-lipoksigenaza, arahidonska kiselina 5-lipoksigenaza, C-5-lipoksigenaza, LTA sintaza, leukotrienska A4 sintaza) je enzim sa sistematskim imenom arachidonat:kiseonik 5-oksidoreduktaza.[1][2][3][4] Ovaj enzim katalizuje sledeću hemijsku reakciju
- arahidonat + O2 leukotrien A4 + H2O (sveukupna reakcija)
- (1a) arahidonat + O2 (6E,8Z,11Z,14Z)-(5S)-5-hidroperoksiikosa-6,8,11,14-tetraenoat
- (1b) (6E,8Z,11Z,14Z)-(5S)-5-hidroperoksiikosa-6,8,11,14-tetraenoat leukotrien A4 +H2O
