This article may require cleanup to meet Wikipedia's quality standards. The specific problem is: Need to explain the deletion of EC due to being "covered by EC 7.1.1.2" (the ubiquinone one). Such a merge makes sense for some proteins tagged with that EC, but definitely does not make sense for this article. Please help improve this article if you can.

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 1.6.5.11) is defined for NADH dehydrogenases that use a quinone (excluding ubiquinone) as the acceptor. The EC term NADH dehydrogenase (ubiquinone) (EC 7.1.1.2) is defined for those with ubiquinone as the acceptor.
