Bacteriorhodopsin(bR) is a transmembrane protein in the purple membrane of Ha1obacterium halobium. It pumps protons across the membrane using light energy absorbed by retinal in it. Although the mechanism of the proton pump has been the subject of considerable investigation, the relations between the mechanism and bR protein structure are obscure, yet.
