bacteriorhodopsin[bak‚tir·ē·ō·rō′däp·sən] (biochemistry) A purple substance in the cell membranes of halobacteria (found in extremely saline environments) during conditions of low oxygen, and consisting of the protein bacteriopsin and retinal, the same carotenoid found in the visual pigments of animals; in response to light, the purple membrane pumps protons out of the cell, providing the energy gradient for synthesis of adeniosine triphosphate. bacteriorhodopsinenUK
