NADH dehydrogenase [ubiquinone] iron-sulfur protein 3, mitochondrial (NDUFS3)

Core subunit of the mitochondrial membrane respiratory chain NADH dehydrogenase (Complex I) that is believed to belong to the minimum assembly required for catalysis. Complex 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 (By similarity). .
