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       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}.
