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 + H+ + acceptor ⇌ NAD+ + reduced acceptor

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 is defined for NADH dehydrogenases that use a quinone (excluding ubiquinone) as the acceptor. The EC term NADH dehydrogenase (ubiquinone) (EC is defined for those with ubiquinone as the acceptor.
