Function
function
This enzyme is required for electron transfer from NADP to cytochrome P450 in microsomes. It can also provide electron transfer to heme oxygenase and cytochrome B5. Involved in ergosterol biosynthesis.
Catalytic activity
- 2 oxidized [cytochrome P450] + NADPH = 2 reduced [cytochrome P450] + NADP+ + H+
Cofactor
Protein has several cofactor binding sites:
Note: Binds 1 FAD per monomer.
Note: Binds 1 FMN per monomer.
