## Abstract Halobacterium halobium carries out photophosphorylation. A rhodopsin‐like protein, bacteriorhodopsin, located in the cell membrane mediates the first step in energy transduction, the conversion of light energy into a chemiosmotic gradient. After absorption of a photon, bacteriorhodopsin
## Abstract Light‐induced sodium extrusion from H halobium cell envelope vesicles proceeds largely through an uncoupler‐sensitive pathway involving bacteriorhodopsin and a proton/sodium antiporter. Vesicles from bacteriorhodopsin‐negative strains also extrude sodium ions during illumination, but th
