Multidrug transport protein norM from vibrio cholerae simultaneously couples to sodium- and proton-motive force.

Abstract excerpt

Membrane transporters belonging to the multidrug and toxic compound extrusion family mediate the efflux of unrelated pharmaceuticals from the interior of the cell in organisms ranging from bacteria to human. These proteins are thought to fall into two classes that couple substrate efflux to the influx of either Na(+) or H(+). We studied the energetics of drug extrusion by NorM from Vibrio cholerae in...
