Protein attributes

Sequence length	464 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level.

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.
Catalytic activity	NADPH + NAD(+) = NADP(+) + NADH.
Cofactor	Binds 1 FAD per subunit.
Enzyme regulation	Strongly activated by NADPH and 2'-AMP and inhibited by NADP(+). Ca(2+) increases the activation and decreases the inhibition effect.
Subunit structure	Homooligomer; probably composed of four stacked rings of 7 or 8 monomers. Forms filamentous structures.
Subcellular location	CytoplasmBy similarity.
Sequence similarities	Belongs to the class-I pyridine nucleotide-disulfide oxidoreductase family.
