Function
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.
Catalytic activity
- a ubiquinone + 5 H+(in) + NADH = a ubiquinol + 4 H+(out) + NAD+
a ubiquinone RHEA-COMP:9565 + 5 H+ (in)CHEBI:15378+ CHEBI:57945 = a ubiquinol RHEA-COMP:9566 + 4 H+ (out)CHEBI:15378+ CHEBI:57540
