|
| Comment(s) |
|---|
- This enzyme catalyzes the transfer of electrons from NADPH,
an obligatory two-electron donor, to microsomal P450 monooxygenases
(e.g. EC 1.14.14.1) by stabilizing the one-electron reduced form of
the flavin cofactors FAD and FMN.
- It also reduces cytochrome b5 and cytochrome c.
- The number n in the equation is 1 if the hemoprotein undergoes a
2-electron reduction, and is 2 if it undergoes a 1-electron
reduction.
