The polar lipids of the purple membrane were exchanged for different phosphatidylcholine species. The resulting complexes had the same protein to lipid-phosphorus ratio as the natural membrane, but only about 0.5-1.0 mole of original lipid was still present per mole of bacteriorhodopsin. In such complexes the bacteriorhodopsin photocycle is slowed down 10… CONTINUE READING
