Family relationships



This entry describes the 14th (based on Escherichia coli) structural gene, N, of bacterial and chloroplast energy-transducing NADH (or NADPH) dehydrogenases (EC: This entry does not describe any subunit of the mitochondrial complex I (for which the subunit composition is very different), nor NADH dehydrogenases that are not coupled to ion transport. For chloroplast members, the name NADH-plastoquinone oxidoreductase is used for the complex and this protein is designated as subunit 2 or B. This entry also includes a subunit of a related complex in the archaeal methanogen, Methanosarcina mazei (Methanosarcina frisia), in which F420H2 replaces NADH and 2-hydroxyphenazine replaces the quinone.
