摘要：

Halorhodopsin, a light-driven halide pump, is the second archaeal rhodopsin involved in ion pumping to be studied at high resolution by X-ray crystallography, Like its cousin bacteriorhodopsin, halorhodopsin couples vectorial ion transport to the isomerisation state of a covalently linked retinal. Given the similarity and interconvertability of these two ion pumps, a unified mechanism for ion translocation by archaeal rhodopsins is now emerging.
