Function

Bacteriorhodopsin (Br) is a membrane protein in Archaea which moves protons across the cell membrane.

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 with hydrophobic and aromatic residues.
