Reaction: NADH + H+ + acceptor = NAD+ + reduced acceptor
Other name(s): cytochrome c reductase; type 1 dehydrogenase; β-NADH dehydrogenase dinucleotide; diaphorase; dihydrocodehydrogenase I dehydrogenase; dihydronicotinamide adenine dinucleotide dehydrogenase; diphosphopyridine diaphorase; DPNH diaphorase; NADH diaphorase; NADH hydrogenase; NADH oxidoreductase; NADH-menadione oxidoreductase; reduced diphosphopyridine nucleotide diaphorase; NADH:cytochrome c oxidoreductase; NADH2 dehydrogenase; NADH:(acceptor) oxidoreductase
Systematic name: NADH:acceptor oxidoreductase
Comments: A flavoprotein containing iron-sulfur centres. After preparations have been subjected to certain treatments, cytochrome c may act as an acceptor. Under normal conditions, two protons are extruded from the cytoplasm or the intramitochondrial or stromal compartment. Formerly EC 18.104.22.168; present in a mitochondrial complex as EC 22.214.171.124 NADH dehydrogenase (ubiquinone).
