This entry represents a group of uncharacterised proteins, such as the 9.3kDa protein YNQ1 from the nqo2 3'region in Paracoccus denitrificans. They have no known function.
Respiratory-chain NADH dehydrogenase () [](also known as complex I or NADH-ubiquinone oxidoreductase) is an oligomeric enzymatic complex located in the inner mitochondrial membrane which also seems to exist in the chloroplast and in cyanobacteria (as a NADH-plastoquinone oxidoreductase). Among the 25 to 30 polypeptide subunits of this bioenergetic enzyme complex there is one with a molecular weight of 24 Kd (in mammals), which is a component of the iron-sulfur (IP) fragment of the enzyme. It seems to bind a 2Fe-2S iron-sulfur cluster. The 24 Kd subunit is nuclear encoded, as a precursor form with a transit peptide in mammals, and in Neurospora crassa.The 24 Kd subunit is highly similar to [, ]: Subunit E of Escherichia coli NADH-ubiquinone oxidoreductase (gene nuoE) and Subunit NQO2 of Paracoccus denitrificans NADH-ubiquinone oxidoreductase.
