    Functioni

    Core subunit of the mitochondrial membrane respiratory chain NADH dehydrogenase (Complex I) that is believed to belong to the minimal assembly required for catalysis. Complex I functions in the transfer of electrons from NADH to the respiratory chain. The immediate electron acceptor for the enzyme is believed to be ubiquinone By similarity. May donate electrons to ubiquinone.By similarity

    Catalytic activityi

    NADH + ubiquinone + 5 H+(In) = NAD+ + ubiquinol + 4 H+(Out).
    NADH + acceptor = NAD+ + reduced acceptor.

    Cofactori

    Binds 2 4Fe-4S clusters per subunit.By similarity
