Interpro abstract (IPR009866): | This family contains human NADH-ubiquinone oxidoreductase subunit NDUFB4 and related sequences. NADH:ubiquinone oxidoreductase (complex I) ( EC 1.6.5.3 ) 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) [ (PUBMED:1470679) ]. 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 [ (PUBMED:10940377) ], 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 [ (PUBMED:18394423) ]. |
