NADH dehydrogenase [ubiquinone] iron-sulfur protein 2, mitochondrial (NDUFS2)

Core subunit of the mitochondrial membrane respiratory chain NADH dehydrogenase (Complex I) that is thought to belong to the minimal assembly required for catalysis. Sophisticated I works in the transport of electrons from NADH to the respiratory chain.

The immediate electron acceptor for the enzyme is believed to be ubiquinone (PubMed:12611891). .
