See also Bacteriorhodopsin (Hebrew). Structural highlights Br is composed of 6 α-helical elements each containing a retinal molecule. The retinal changes its ground state conformation upon binding of a proton, causing the Br to change conformation to the activated state and pump the proton. The retinal interacts predominantly with hydrophobic and aromatic residues (Hydrophobic, Polar).
