CC -!- FUNCTION: A cytochrome P450 monooxygenase involved in the metabolism of
CC fatty acids. 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 (NADPH--hemoprotein reductase). Catalyzes the hydroxylation
CC of carbon-hydrogen bonds. Hydroxylates fatty acids specifically at the
CC omega-1 position displaying the highest catalytic activity for
CC saturated fatty acids. May be involved in the oxidative metabolism of
CC xenobiotics. {ECO:0000250|UniProtKB:P05181}.
