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. UniProtKB P16435
Catalytic activity	NADPH + n oxidized hemoprotein = NADP+ + n reduced hemoprotein.
Cofactor	FAD By similarity. FMN By similarity.
Subcellular location	Endoplasmic reticulum membrane; Single-pass membrane protein By similarity.
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.
