Bacteriorhodopsin (bR) is the protein found in the purple membrane of halobacteria, and it functions as a light-driven proton pump. It comprises a polypeptide chain of 248 amino acids and a light-absorbing chromophore retinal attached to one of the lysine residues. The protein is present in the purple membrane together with lipid molecules and forms a very well ordered two-dimensional array (Oesterhelt and Stoeckenius, 1971; Blaurock and Stoeckenius, 1971).
