CC   -!- FUNCTION: Electron donor reductase for cytochrome b5. The
CC       cytochrome b5/NADH cytochrome b5 reductase electron transfer
CC       system supports the catalytic activity of several sterol
CC       biosynthetic enzymes (By similarity).
CC   -!- CATALYTIC ACTIVITY: NADH + 2 ferricytochrome b5 = NAD(+) + H(+) +
CC       2 ferrocytochrome b5.
CC   -!- COFACTOR: FAD (By similarity).
CC   -!- SUBUNIT: Monomer (By similarity).
CC   -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane; Single-pass
CC       membrane protein (By similarity). Mitochondrion outer membrane;
CC       Single-pass membrane protein (By similarity).
CC   -!- SIMILARITY: Belongs to the flavoprotein pyridine nucleotide
CC       cytochrome reductase family.
CC   -!- SIMILARITY: Contains 1 FAD-binding FR-type domain.
