None.

Description

This entry represents the subunit 10 (also known as CI-42kD) of the mitochondrial membrane respiratory chain NADH dehydrogenase (Complex I). It is an accessory subunit that is believed not to be involved in catalysis [PMID: 9878551].

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) [PMID: 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 [PMID: 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 [PMID: 18394423].
