Protein name |
RecName:
|
Full=Na(+)-translocating NADH-quinone reductase subunit B;
|
|
Short=Na(+)-NQR subunit B;
|

AltName:
|
Full=NQR complex subunit B;
|
AltName:
|
Full=NQR-1 subunit B;
|
|
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 |
RHEA:47748: a ubiquinone + H(+) + n Na(+)(in) + NADH = a ubiquinol + n Na(+)(out) + NAD(+)
