CYP4F8 [ENSP00000477567]
Cytochrome P450 4F8; A cytochrome P450 monooxygenase involved in the metabolism of endogenous polyunsaturated fatty acids (PUFAs) and their oxygenated derivatives (oxylipins). Mechanistically, uses molecular oxygen inserting one oxygen atom into a substrate, and reducing the second into a water molecule, with two electrons provided by NADPH via cytochrome P450 reductase (CPR; NADPH-ferrihemoprotein reductase). Catalyzes the hydroxylation of carbon hydrogen bonds, with preference for omega-1 and omega-2 positions (PubMed:10791960, PubMed:16112640, PubMed:15789615). Hydroxylates (5Z,8Z,11Z,14Z)-eicosatetraenoic acid (arachidonate) predominantly at omega-2 position to form (18R)- hydroxyeicosatetraenoic acid (18R-HETE) . Exhibits omega-1 hydroxylase activity toward prostaglandin (PG) H1, PGH2 and PGI2 . Catalyzes the epoxidation of double bonds of PUFAs, including docosahexaenoic and docosapentaenoic acids . Shows little activity against PGD2, PGE1, PGE2, PGF2alpha, and leukotriene B4.
