| Short Name | NDUFAF3/AAMDC |
| description | This entry includes NDUFAF3, an essential factor for the assembly of mitochondrial NADH:ubiquinone oxidoreductase complex (complex I) [], and the Mth938 domain-containing protein []. The crystal structure of NDUFAF3 revealed a 3-layer beta+alpha/beta/alpha topology [].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 []. |
