NADH-ubiquinone oxidoreductase chain 4L (Mtnd4l)

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). .
