---|---|
Synonyms: | H+-thase, NAD transhydrogenase, NAD(P) transhydrogenase (B-specific) activity, NADH transhydrogenase, NADH-NADP-transhydrogenase, NADPH-NAD oxidoreductase, NADPH-NAD transhydrogenase, NADPH:NAD+ oxidoreductase (B-specific), NADPH:NAD+ transhydrogenase, nicotinamide adenine dinucleotide (phosphate) transhydrogenase, nicotinamide nucleotide transhydrogenase activity, non-energy-linked transhydrogenase activity, pyridine nucleotide transferase, pyridine nucleotide transhydrogenase activity |
Definition: | 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+. |
