CC -!- FUNCTION: This enzyme is required for electron transfer from NADP to
CC cytochrome P450 in microsomes. It can also provide electron transfer to
CC heme oxygenase and cytochrome B5. {ECO:0000256|HAMAP-Rule:MF_03212}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=NADPH + 2 oxidized [cytochrome P450] = H(+) + NADP(+) + 2
CC reduced [cytochrome P450]; Xref=Rhea:RHEA:24040, Rhea:RHEA-

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.

CC -!- SIMILARITY: In the C-terminal section; belongs to the flavoprotein
CC pyridine nucleotide cytochrome reductase family. {ECO:0000256|HAMAP-
CC Rule:MF_03212, ECO:0000256|PIRNR:PIRNR000208}.
CC -!- SIMILARITY: In the N-terminal section; belongs to the flavodoxin
CC family. {ECO:0000256|HAMAP-Rule:MF_03212}.
