  • The general scheme of electron flow in the POR/P450 system is: NADPH → FAD → FMN → P450 → O2 The definitive evidence for the requirement of POR in cytochrome-P450-mediated reactions came from the work of Lu, Junk and Coon, who dissected the P450-containing mixed function oxidase system into three constituent components: POR, cytochrome P450, and lipids.
