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:0000255|HAMAP-Rule:MF_00429}.
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         Rule:MF_00429};
CC   -!- SUBUNIT: Composed of six subunits; NqrA, NqrB, NqrC, NqrD, NqrE and
CC       NqrF. {ECO:0000255|HAMAP-Rule:MF_00429}.
CC   -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000255|HAMAP-
CC       Rule:MF_00429}; Multi-pass membrane protein {ECO:0000255|HAMAP-
CC       Rule:MF_00429}.
CC   -!- SIMILARITY: Belongs to the NqrDE/RnfAE family. {ECO:0000255|HAMAP-
CC       Rule:MF_00429}.
