show Brenda entry

EC number

1.6.1.3

Accepted name

NAD(P)⁺ transhydrogenase

Reaction

NADPH + NAD⁺ = NADP⁺ + NADH

Other name(s)

pyridine nucleotide transhydrogenase, transhydrogenase (ambiguous), nicotinamide adenine dinucleotide (phosphate) transhydrogenase (ambiguous), NAD⁺ transhydrogenase (ambiguous), NADH transhydrogenase (misleading), nicotinamide nucleotide transhydrogenase (ambiguous), NADPH-NAD⁺ transhydrogenase (ambiguous), pyridine nucleotide transferase (ambiguous), NADPH-NAD⁺ oxidoreductase (ambiguous), NADH-NADP⁺-transhydrogenase (ambiguous), NADPH:NAD⁺ transhydrogenase, H⁺-Thase (ambiguous), non-energy-linked transhydrogenase (ambiguous)

Systematic name

NADPH:NAD⁺ oxidoreductase

Comment

The enzyme catalyses the NADPH-driven reduction of NAD⁺. This entry stands for enzymes whose stereo-specificity with respect to NADPH is not known. [cf. EC 1.6.1.1, NAD(P)⁺ transhydrogenase (Si-specific) and EC 1.6.1.2 NAD(P)⁺ transhydrogenase (Re/Si-specific)].
