4,4'-diapofitoen desaturaza (EC 1.3.8.2, dehidroskvalenska desaturaza, CrtN, 4,4'-diapofitoen:FAD oksidoreduktaza) je enzim sa sistematskim imenom 15-cis-4,4'-diapofitoen:FAD oksidoreduktaza.[1][2][3] Ovaj enzim katalizuje sledeću hemijsku reakciju
- 15-cis-4,4'-diapofitoen + 4 FAD sve--trans-4,4'-diapolikopen + 4 FADH2 (sveukupna reakcija)
- (1a) 15-cis-4,4'-diapofitoen + FAD sve-trans-4,4'-diapofitofluen + FADH2
- (1b) sve-trans-4,4'-diapofitofluen + FAD sve-trans-4,4'-diapo-zeta-karoten + FADH2
- (1c) sve-trans-4,4'-diapo-zeta-karoten + FAD sve-trans-4,4'-diaponeurosporen + FADH2
- (1d) sve-trans-4,4'-diaponeurosporen + FAD sve-trans-4,4'-diapolikopen + FADH2
Ovaj enzim je tipičan za Staphylococcus aureus i neke druge bakterije kao što je Heliobacillus sp. On je odgovoran za četiri sukcesivne dehidrogenacije.
