摘　　要：Bacteriorhodopsin （bR） in purple membrane （PM） from H. Halobium is a light-drivenproton pump. Its seven transmembrane helices form an internal proton channel. Anall-trans retinal covalently links up via protonated Schiff base with K216 inside thechannel. Upon illumination, the retinal isomerization around the C₁₃-C₁₄ double bond drivesprotons translocation through the channel from the cytoplasm into the medium, and
