Rhodopsin and other proteins in artificial lipid membranes

Some basic aspects of incorporation of hydrophobic peptides and proteins in artificial lipid membranes are discussed. As examples valinomycin as a carrier model and gramicidin A as a channel former in lipid vesicles and in planar lipid membranes are presented.In the second part of the lecture some examples of incorporation of membrane proteins into lipid vesicles and planar lipid membranes are reported. The interaction with artificial lipid membranes of the Ca⁺ ATPase from the sarcoplasmic reticulum, of Rhodopsin, and of Bacteriorhodopsin is presented.Presented at the EMBO-Workshop on Transduction Mechanism of Photoreceptors, Jülich, Germany, October 4–8, 1976
