CC -!- FUNCTION: Conversion of NADPH, generated by peripheral catabolic
CC pathways, to NADH, which can enter the respiratory chain for energy
CC generation. {ECO:0000255|HAMAP-Rule:MF_00247}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=NAD(+) + NADPH = NADH + NADP(+); Xref=Rhea:RHEA:11692,
CC ChEBI:CHEBI:57540, ChEBI:CHEBI:57783, ChEBI:CHEBI:57945,
CC ChEBI:CHEBI:58349; EC=1.6.1.1; Evidence={ECO:0000255|HAMAP-
CC Rule:MF_00247};
CC -!- COFACTOR:
CC Name=FAD; Xref=ChEBI:CHEBI:57692;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00247};
CC Note=Binds 1 FAD per subunit. {ECO:0000255|HAMAP-Rule:MF_00247};
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00247}.
CC -!- SIMILARITY: Belongs to the class-I pyridine nucleotide-disulfide
CC oxidoreductase family. {ECO:0000255|HAMAP-Rule:MF_00247}.
