CC -!- FUNCTION: A cytochrome P450 monooxygenase involved in the metabolism of
CC various endogenous substrates, including fatty acids, steroid hormones
CC and vitamins. Mechanistically, uses molecular oxygen inserting one
CC oxygen atom into a substrate, and reducing the second into a water
CC molecule, with two electrons provided by NADPH via cytochrome P450
CC reductase (CPR; NADPH-ferrihemoprotein reductase). Catalyzes the
CC hydroxylation of carbon-hydrogen bonds. Exhibits high catalytic
CC activity for the formation of hydroxyestrogens from estrone (E1) and
CC 17beta-estradiol (E2), namely 2-hydroxy E1 and E2, as well as D-ring
CC hydroxylated E1 and E2 at the C15alpha and C16alpha positions. Displays
CC different regioselectivities for polyunsaturated fatty acids (PUFA)
CC hydroxylation. Catalyzes the epoxidation of double bonds of certain
CC PUFA. Converts arachidonic acid toward epoxyeicosatrienoic acid (EET)
CC regioisomers, 8,9-, 11,12-, and 14,15-EET, that function as lipid
CC mediators in the vascular system. Displays an absolute
CC stereoselectivity in the epoxidation of eicosapentaenoic acid (EPA)
CC producing the 17(R),18(S) enantiomer. May play an important role in
CC all-trans retinoic acid biosynthesis in extrahepatic tissues. Catalyzes
CC two successive oxidative transformation of all-trans retinol to all-
CC trans retinal and then to the active form all-trans retinoic acid. May
CC also participate in eicosanoids metabolism by converting hydroperoxide
CC species into oxo metabolites (lipoxygenase-like reaction, NADPH-
CC independent). {ECO:0000250|UniProtKB:P04798}.
