[[Cytochrome P450]] (P450) catalyzes the oxidation of organic substances like lipids. catalyzes the oxidation of organic substances like lipids. The P450 contains a heme cofactor. The protein is numbered by its gene. P450cam, also known as camphor 5-monooxygenase, catalyzes the hydroxylation of camphor. P450nor is a Nitric Oxide Reductase P450. P450epoK converts epothilone D to epothilone B. P450cin monooxygenates 1,8-cineole which is similar to camphor. The images at the left and at the right correspond to one representative P450, ''i.e.'' the crystal structure of human P4502 ([[2f9q]]). For details on the human P45019 family see [[Aromatase]]. Bifunctional P450/NADPH P450 reductase is a fatty acid monooxygenase. Additional details in [[Drug Metabolism by CYP450 Enzymes]].
