    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. Component of the iron-sulfur (IP) fragment of the enzyme. Component of the iron-sulfur (IP) fragment of the enzyme.By similarity

    Catalytic activityi

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