General annotation (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 By similarity. HAMAP-Rule MF_00430

Catalytic activity

NADH + ubiquinone + Na+(In) = NAD+ + ubiquinol + Na+(Out). HAMAP-Rule MF_00430

Cofactor

Binds 1 2Fe-2S cluster By similarity. HAMAP-Rule MF_00430

FAD By similarity. HAMAP-Rule MF_00430

Subunit structure

Composed of six subunits; NqrA, NqrB, NqrC, NqrD, NqrE and NqrF By similarity.

Subcellular location

Cell inner membrane Potential HAMAP-Rule MF_00430.

Sequence similarities

Belongs to the NqrF family.

Contains 1 2Fe-2S ferredoxin-type domain.

Contains 1 FAD-binding FR-type domain.
