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. NqrA to NqrE are
CC probably involved in the second step, the conversion of ubisemiquinone
CC to ubiquinol. {ECO:0000256|HAMAP-Rule:MF_00425}.
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,

CC ChEBI:CHEBI:17976, ChEBI:CHEBI:29101, ChEBI:CHEBI:57540,
CC ChEBI:CHEBI:57945; EC=7.2.1.1; Evidence={ECO:0000256|HAMAP-
CC Rule:MF_00425};
CC -!- SUBUNIT: Composed of six subunits; NqrA, NqrB, NqrC, NqrD, NqrE and
CC NqrF. {ECO:0000256|HAMAP-Rule:MF_00425}.
CC -!- SIMILARITY: Belongs to the NqrA family. {ECO:0000256|HAMAP-
CC Rule:MF_00425}.
