The P450 contains a heme cofactor. The protein is numbered by its gene.[1] P450 CYP121 is called mycocyclosin synthase. P450cam, also known as camphor 5-monooxygenase, catalyzes the hydroxylation of camphor[2]. P450nor is a Nitric Oxide Reductase P450[3]. P450epoK converts epothilone D to epothilone B[4]. P450cin monooxygenates 1,8-cineole which is similar to camphor[5]. Bifunctional P450/NADPH P450 reductase (P450 BM3) is a fatty acid monooxygenase. P450 3A4 see CYP3A4. P450 19 family see Aromatase. P450 17A1 see Human steroidogenic cytochrome P450 17A1 with inhibitor abiraterone See also Hemeproteins. Additional details on cytochrome P450 interactions with drugs see Drug Metabolism by CYP450 Enzymes Montelukast - anti rhinitis Noxafil - antifungal drug which binds to CYP51. Cobicistat - anti HIV/AIDS drug which binds to CYP3A4. Structural highlights The . The .[6] 3D Structures of Cytochrome P450 Cytochrome P450 3D structures
