| Outline of Final Research Achievements |
Energy conversion and water oxidation in photosynthesis are quite efficiently performed in plants and cyanobacteria. Understanding about these molecular mechanisms based on the molecular structure must be important subject not only from scientific point of view but also from the view point of new energy creation. Especially understanding relationship between molecular structure and function of Photosystem II, which plays initial reaction of photosynthetic electron transfer and water oxidation, is one of the most important subject. Although analyses of site-directed mutants are quite powerful approaches, we have not obtained important mutants of thermophilic cyanobacterial because of loss of photosynthetic function by mutations. For solution of these serious problems, in this study, we established new genetic engineering system of the thermophilic cyanobacterium, Thermosynechococcus elongatus.
