Chain A,B (PNTAA_RHORT | Q2RSB2)

molecular function
	GO:0051287	NAD binding	Interacting selectively and non-covalently with nicotinamide adenine dinucleotide, a coenzyme involved in many redox and biosynthetic reactions; binding may be to either the oxidized form, NAD+, or the reduced form, NADH.
	GO:0008750	NAD(P)+ transhydrogenase (AB-specific) activity	Catalysis of the reaction: NADPH + H+ + NAD+ = NADP+ + NADH + H+. The reaction is A-specific (i.e. the pro-R hydrogen is transferred from the 4-position of reduced nicotinamide cofactor) with respect to NAD+ and B-specific (i.e. the pro-S hydrogen is transferred) with respect to NADP+.
	GO:0003957	NAD(P)+ transhydrogenase (B-specific) activity	Catalysis of the reaction: NADPH + H+ + NAD+ = NADP+ + NADH + H+, driving the transfer of a solute or solutes from one side of a membrane to the other. In the course of the reaction (left to right) one H atom is transferred from inside the cell to outside. The reaction is B-specific (i.e. the pro-S hydrogen is transferred from the 4-position of reduced nicotinamide cofactor) with respect to both NAD+ and NADP+.
	GO:0070403	NAD+ binding	Interacting selectively and non-covalently with the oxidized form, NAD, of nicotinamide adenine dinucleotide, a coenzyme involved in many redox and biosynthetic reactions.
	GO:0070404	NADH binding	Interacting selectively and non-covalently with the reduced form, NADH, of nicotinamide adenine dinucleotide, a coenzyme involved in many redox and biosynthetic reactions.
	GO:0000166	nucleotide binding	Interacting selectively and non-covalently with a nucleotide, any compound consisting of a nucleoside that is esterified with (ortho)phosphate or an oligophosphate at any hydroxyl group on the ribose or deoxyribose.
	GO:0016491	oxidoreductase activity	Catalysis of an oxidation-reduction (redox) reaction, a reversible chemical reaction in which the oxidation state of an atom or atoms within a molecule is altered. One substrate acts as a hydrogen or electron donor and becomes oxidized, while the other acts as hydrogen or electron acceptor and becomes reduced.
	GO:0005515	protein binding	Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
	GO:0046983	protein dimerization activity	The formation of a protein dimer, a macromolecular structure consists of two noncovalently associated identical or nonidentical subunits.
biological process
	GO:0006740	NADPH regeneration	A metabolic process that generates a pool of NADPH by the reduction of NADP+.
	GO:1902600	hydrogen ion transmembrane transport	The directed movement of hydrogen ion (proton) across a membrane.
	GO:0055114	oxidation-reduction process	A metabolic process that results in the removal or addition of one or more electrons to or from a substance, with or without the concomitant removal or addition of a proton or protons.
