## Abstract Lightโinduced sodium extrusion from H halobium cell envelope vesicles proceeds largely through an uncouplerโsensitive pathway involving bacteriorhodopsin and a proton/sodium antiporter. Vesicles from bacteriorhodopsinโnegative strains also extrude sodium ions during illumination, but th
## Abstract Cell envelope vesicles prepared from H. halobium contain bacteriorhodopsin and upon illumination protons are ejected. Coupled to the proton motive force is the efflux of Na^+^.
