Identifier
NQRF
Protein name
RecName: Full=Na(+)-translocating NADH-quinone reductase subunit F;
Short=Na(+)-NQR subunit F;

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. The first step is catalyzed by NqrF, which accepts electrons from NADH and reduces ubiquinone-1 to ubisemiquinone by a one-electron transfer pathway.
Catalytic activity RHEA:47748: a ubiquinone + H(+) + n Na(+)(in) + NADH = a ubiquinol + n Na(+)(out) + NAD(+)
EC 7.2.1.1
Cofactor [2Fe-2S] cluster
Note: Binds 1 [2Fe-2S] cluster.
