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,
