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.
COFACTOR: FMN.
SUBCELLULAR LOCATION: Endoplasmic reticulum membrane; Peripheral membrane protein. Note=Anchored to the ER membrane by its N-terminal hydrophobic region.
SIMILARITY: In the C-terminal section; belongs to the flavoprotein pyridine nucleotide cytochrome reductase family.
SIMILARITY: Contains 1 FAD-binding FR-type domain.
SIMILARITY: Contains 1 flavodoxin-like domain.
CAUTION: Was originally (Ref.1) thought to originate from mouse.
