General annotation (Comments)

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.

Catalytic activity

NADPH + n oxidized hemoprotein = NADP+ + n reduced hemoprotein.

Cofactor

FAD.

FMN.

Subcellular location

Endoplasmic reticulum membrane; Peripheral membrane protein. Note: Anchored to the ER membrane by its N-terminal hydrophobic region.

Sequence similarities

In the C-terminal section; belongs to the flavoprotein pyridine nucleotide cytochrome reductase family.

Contains 1 FAD-binding FR-type domain.

Contains 1 flavodoxin-like domain.
