CC Note=Binds 1 FAD per monomer. {ECO:0000256|HAMAP-Rule:MF_03212};
CC -!- COFACTOR:
CC Name=FMN; Xref=ChEBI:CHEBI:58210;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_03212};
CC Note=Binds 1 FMN per monomer. {ECO:0000256|HAMAP-Rule:MF_03212};
CC -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane
CC {ECO:0000256|HAMAP-Rule:MF_03212}; Single-pass membrane protein
CC {ECO:0000256|HAMAP-Rule:MF_03212}; Cytoplasmic side {ECO:0000256|HAMAP-
CC Rule:MF_03212}.
CC -!- SIMILARITY: Belongs to the NADPH--cytochrome P450 reductase family.
