Outline of Final Research Achievements

For production of membrane protein, liposome integrated PURE system was developed. Using this system, bacteriorhodopsin and FoF1-ATP synthase were successfully expressed onto lipid bilayer. While bacteriorhodopsin expressed onto liposome composed of soy bean extract exhibited proton-pumping activities, artificial liposome such as POPC cannot provided scaffold for the activity of bacteriorhodopsin. Concerning FoF1-ATP synthase, amount of template DNA for individual subunit was optimized for the synthesis of active ATPase. Both synthesized bacteriorhodopsin and ATPase were evaluated by measuring enzymatic activities. To synthesize photosynthetic cell, the Gigantic Unilamellar Vesicle (GUV) containing the Small Unilamellar Vesicles (SUV) onto which bacteriorhodopsin and FoF1-ATP synthase were translocated, were developed.
