NADH dehydrogenase [ubiquinone] iron-sulfur protein 7 mitochondrial also knowns as NADH-ubiquinone oxidoreductase 20 kDa subunit is an enzyme that in humans is encoded by the NDUFS7 gene.The PSST subunit is highly conserved across evolutionary distances. Crystal structures and mutational studies indicate that it is one of the ubiquinone binding sites of Complex I together with the TYKY (NDUFS8) subunit.
