>cd02771 MopB_NDH-1_NuoG2-N7 MopB_NDH-1_NuoG2-N7: The second domain of the NuoG subunit (with a [4Fe-4S] cluster, N7) of the NADH-quinone oxidoreductase/NADH dehydrogenase-1 (NDH-1) found in various bacteria. The NDH-1 is the first energy-transducting complex in the respiratory chain and functions as a redox pump that uses the redox energy to translocate H+ ions across the membrane, resulting in a significant contribution to energy production. In Escherichia coli NDH-1, the largest subunit is encoded by the nuoG gene, and is part of the 14 distinct subunits constituting the functional enzyme. The NuoG subunit is made of two domains: the first contains three binding sites for FeS clusters (the fer2 domain), the second domain (this CD), is of unknown function or, as postulated, has lost an ancestral formate dehydrogenase activity that became redundant during the evolution of the complex I enzyme. Unique to this group, compared to the other prokaryotic and eukaryotic groups in this domain
