| Research Abstract |
Photosystem II (PSII) catalyzes the oxygen evolution from water in the photosynthesis utilizing solar light energy. We succeeded to determine, first in the world, the three-dimensional structure of the oxygen-evolving Mn4Ca cluster at atomic resolution, including the whole structure of PSII. Because PSII also provides chemical energy for CO2 condensation, our results serve structural strict-bases for efficient use of solar energy in the green chemistry.
