Bacteriorhodopsin (Bop) is a protein used by Archaea, most notably by haloarchaea, a class of the Euryarchaeota.[1] It acts as a proton pump; that is, it captures light energy and uses it to move protons across the membrane out of the cell.[2] The resulting proton gradient is subsequently converted into chemical energy.[3]
