| Research Abstract |
We purified the reaction center complexes involved in oxygenic photosynthesis and determined their subunits and cofactors, and crystalized them to determine the three-dimensional structures. We also examined the molecular mechanism by which the reaction center complexes are assembled from the constituent subunits and cofactors and proposed a working model for the assembly. Furthermore, we revealed the molecular mechanism by which the structure and function of the reaction center complexes are remodeled under varying light environments.
