GO Classification
NADH dehydrogenase (ubiquinone) activity
cellular metabolic process / mitochondrial electron transport, NADH to ubiquinone / respiratory electron transport chain / small molecule metabolic process
integral component of membrane / mitochondrial inner membrane / mitochondrial respiratory chain complex I
General Function
Nadh dehydrogenase (ubiquinone) activity
Specific Function
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).
