== Function == | |||
'''Bacteriorhodopsin''' (Br) is a membrane protein in Archaea which moves protons across the cell membrane. Br is composed of 6 α-helical elements each containing a retinal molecule. The retinal changes its conformation upon binding of a proton, causing the Br to change conformation and pump the proton. | '''Bacteriorhodopsin''' (Br) is a membrane protein in Archaea which moves protons across the cell membrane. | ||
