General annotation (Comments)

Function	Conversion of NADPH, generated by peripheral catabolic pathways, to NADH, which can enter the respiratory chain for energy generation By similarity. HAMAP MF_00247
Catalytic activity	NADPH + NAD+ = NADP+ + NADH. HAMAP MF_00247
Cofactor	Binds 1 FAD per subunit By similarity. HAMAP MF_00247
Subunit structure	Homooligomer; probable homooctamer By similarity. HAMAP MF_00247
