Comments [?]

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	Reaction=a ubiquinone + n Na(+)(in) + NADH + H(+) = a ubiquinol + n Na(+)(out) + NAD(+); Xref=Rhea:RHEA:47748, Rhea:RHEA-COMP:9565, Rhea:RHEA-COMP:9566, ChEBI:CHEBI:15378, ChEBI:CHEBI:16389, ChEBI:CHEBI:17976, ChEBI:CHEBI:29101, ChEBI:CHEBI:57540, ChEBI:CHEBI:57945; EC=7.2.1.1;
SUBUNIT	Composed of six subunits; NqrA, NqrB, NqrC, NqrD, NqrE and NqrF.
case not defined <Property:Membrane> or <Property:Membrane=1>
SUBCELLULAR LOCATION	Cell membrane; Multi-pass membrane protein.
else case <Property:Membrane=2>
SUBCELLULAR LOCATION	Cell inner membrane; Multi-pass membrane protein.
end case
SIMILARITY	Belongs to the NqrDE/RnfAE family.
