NADH dehydrogenase is an enzyme that converts nicotinamide adenine dinucleotide (NAD) from its reduced form (NADH) to its oxidized form (NAD+).
Members of the NADH dehydrogenase family and analogues are commonly systematically named using the format NADH:acceptor oxidoreductase.
[2][3][4][5] The chemical reaction these enzymes catalyze is generally represented with the following equation: NADH dehydrogenase is a flavoprotein that contains iron-sulfur centers.
NADH dehydrogenase is used in the electron transport chain for generation of ATP.
The EC term NADH dehydrogenase (quinone) (EC 1.6.5.11) is defined for NADH dehydrogenases that use a quinone (excluding ubiquinone) as the acceptor.
