Two pumps, one principle: light-driven ion transport in halobacteria.

Abstract

Comparison of the primary structure of the chloride pump halorhodopsin with that of the proton pump bacteriorhodopsin provides insight into light-driven ion transport by retinal proteins. Several conserved amino acid residues in the membrane-spanning region of both proteins and their interaction with different isomerization states of retinal are suggested to be the key element for ion transport in both proteins.
