Enzyme Information
| 1.6.2.4 |
NADPH--hemoprotein reductase.
based on mapping to UniProt P16435
NADPH + n oxidized hemoprotein = NADP(+) + n reduced hemoprotein.
-!- 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.
