On 15th Dec 2016, Mr. Keisuke Kawashima , Department of Applied Chemistry, wins a Excellent Poster Award in the CSJ Poster Presentation Award 2016.

Unlike photosynthesis in green plants, purple photosynthetic bacteria do not evolve O2 in photosynthesis. Both photosynthetic reaction centers have similar electron transfer pathways, using the same quinone molecule (i.e., menaquinone). On the other hand, the redox potential values of the quinones in the two reaction centers differ significantly (~500 mV). In the present study, using theoretical approaches and the protein crystal structures, we clarified the factor that differentiates the redox potential values of the quinones in the two reaction centers.

I would like to thank Professor Ishikita and members of Ishikita lab for discussion and support.I want to work harder to understand the mechanism of photosynthesis.
