Function
function
Core subunit of the mitochondrial membrane respiratory chain NADH dehydrogenase (Complex I) which catalyzes electron transfer from NADH through the respiratory chain, using ubiquinone as an electron acceptor. Part of the enzyme membrane arm which is embedded in the lipid bilayer and involved in proton translocation.
Catalytic activity
- a ubiquinone + 5 H+(in) + NADH = a ubiquinol + 4 H+(out) + NAD+This reaction proceeds in the forward direction.
a ubiquinone RHEA-COMP:9565 + 5 H+ (in)CHEBI:15378+ CHEBI:57945 = a ubiquinol RHEA-COMP:9566 + 4 H+ (out)CHEBI:15378+ CHEBI:57540
