(57) [Summary] [Problem] There is no limitation on the concentration of a surfactant used, the processing operation is simple, the efficiency of protein incorporation is increased, and the photochemical system II protein aggregate has a high water-decomposing activity. The present invention provides an industrially advantageous method for producing a lipid vesicle membrane incorporating a photosynthetic membrane protein, which is maintained at a low temperature. When a photosynthetic membrane protein is incorporated into a lipid vesicle membrane in the presence of a surfactant to produce a lipid vesicle membrane incorporating a photosynthetic membrane protein, an osmotic substance, preferably glycine betaine, is further added. |
