Function
function
NQR complex catalyzes the reduction of ubiquinone-1 to ubiquinol by two successive reactions, coupled with the transport of Na+ ions from the cytoplasm to the periplasm. NqrA to NqrE are probably involved in the second step, the conversion of ubisemiquinone to ubiquinol.
Catalytic activity
- a ubiquinone + H+ + n Na+(in) + NADH = a ubiquinol + n Na+(out) + NAD+
a ubiquinone RHEA-COMP:9565 + CHEBI:15378 + n Na+ (in)CHEBI:29101+ CHEBI:57945 = a ubiquinol RHEA-COMP:9566 + n Na+ (out)CHEBI:29101+ CHEBI:57540
