== Function ==
[https://www.uniprot.org/uniprot/NQRA_VIBC3 NQRA_VIBC3] 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.[HAMAP-Rule:MF_00425]
