NDUFS7

NADH dehydrogenase [ubiquinone] iron-sulfur protein 7, mitochondrial, also knowns as NADH-ubiquinone oxidoreductase 20 kDa subunit, is an is_associated_with::enzyme that in humans is encoded by the NDUFS7 is_associated_with::gene. The NDUFS7 protein is a subunit of is_associated_with::NADH dehydrogenase (ubiquinone), which is located in the is_associated_with::mitochondrial inner membrane and is the largest of the five complexes of the is_associated_with::electron transport chain.

Structure
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 (is_associated_with::NDUFS8) subunit.
