CC -!- FUNCTION: NQR complex catalyzes the reduction of ubiquinone-1 to
CC ubiquinol by two successive reactions, coupled with the transport of
CC Na(+) ions from the cytoplasm to the periplasm. The first step is
CC catalyzed by NqrF, which accepts electrons from NADH and reduces
CC ubiquinone-1 to ubisemiquinone by a one-electron transfer pathway.
CC {ECO:0000256|ARBA:ARBA00002972, ECO:0000256|HAMAP-Rule:MF_00430}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a ubiquinone + H(+) + n Na(+)(in) + NADH = a ubiquinol + n
CC Na(+)(out) + NAD(+); Xref=Rhea:RHEA:47748, Rhea:RHEA-COMP:9565,
