Archaerhodopsin-2 is a retinal protein–carotenoid complex found in the claret membrane of Halorubrum sp. aus-2 and it represents a real adaptation to life at high salt concentrations. In these membranes, three Archaerhodopsin-2 chains form a trimeric structure [http://www.pdb.org/pdb/explore/jmol.do?structureId=2Z55&view=symmetry&bionumber=1], capturing light energy and using it to move protons across the membrane out of the cell. It exists four different chains with different structures: A,B,D,E (they are not represented here). | Archaerhodopsin-2 is a retinal protein–carotenoid complex found in the claret membrane of Halorubrum sp. aus-2 and it represents a real adaptation to life at high salt concentrations.
