NADH:ubiquinone oxidoreductase, respiratory complex I, plays a major role in cellular energy metabolism by coupling electron transfer with proton translocation. Electron transfer is catalyzed by a flavin mononucleotide and a series of iron-sulfur (Fe/S) clusters. As a by-product of the reaction, the...
