Purple membrane

purple membrane

(Science: cell biology) plasma membrane of halobacterium and halococcus, that contains a protein bound carotenoid pigment that absorbs light and uses the energy to translocate protons from the cytoplasm to the exterior. The proton gradient then provides energy for aTP synthesis. The binding protein is called bacteriorhodopsin or purple membrane protein.
