Description | NADH:ubiquinone oxidoreductase (complex I) ( ) is a respiratory-chain enzyme that catalyses the transfer of two electrons from NADH to ubiquinone in a reaction that is associated with proton translocation across the membrane (NADH + ubiquinone = NAD+ + ubiquinol) [ ]. Complex I is a major source of reactive oxygen species (ROS) that are predominantly formed by electron transfer from FMNH(2). Complex I is found in bacteria, cyanobacteria (as a NADH-plastoquinone oxidoreductase), archaea [], mitochondria, and in the hydrogenosome, a mitochondria-derived organelle. In general, the bacterial complex consists of 14 different subunits, while the mitochondrial complex contains homologues to these subunits in addition to approximately 31 additional proteins [].This entry represents chain 6 from NADH:ubiquinone oxidoreductase and NADH-plastoquinone oxidoreductase. Bacterial proton-translocating NADH-quinone oxidoreductase (NDH-1) is composed of 14 different subunits. The chain belonging to this family is a subunit that constitutes the membrane sector of the complex. It reduces ubiquinone to ubiquinol utilising NADH. Plant chloroplastic NADH-plastoquinone oxidoreductase reduces plastoquinone to plastoquinol. Mitochondrial NADH-ubiquinone oxidoreductase from a variety of sources reduces ubiquinone to ubiquinol. |
