| Research Abstract |
Photosynthetic membrane proteins (LH2 and LH1-RC) that play important roles of light harvesting and charge separation were successfully reconstituted into lipid bilayer membrane to investigate the relationship between the assembly structure and their function. The structure of the assembly consisting of LH2 and LH1-RC were clearly observed by atomic force microscopy at the molecular level. The structure likely correlates the function, e.g., energy transfer from LH2 to LH1-RC. The basic findings should provide useful information for highly efficient construction of photoenergy conversion system.
