U.S.-France Cooperative Research: Study of Electrostatic Interactions in Bacteria Photochemical Reaction Center Proteins

这个为期三年的奖项支持纽约城市学院的Marilyn Gunner和法国国家科学研究中心光合细菌实验室的Pierre Sebban在光合作用方面的美法合作研究。他们的研究目的是研究光合细菌反应中心中质子残基与醌之间的相互作用。他们将评估质子摄取和电子转移。这位美国研究者为这次合作带来了计算和理论方面的专业知识。计算将在城市学院进行。这得到了法国实验专家的补充。将对野生型和突变型反应中心进行原位电化学和质子摄取的实验测量。这种理论和实验相结合的努力将促进我们对光合系统中的电子转移和反应中心结构及其功能的理解。这些都是光合作用研究的重要目标。

This three-year award supports U.S.-France cooperative research in photosynthesis between Marilyn Gunner of City College of New York and Pierre Sebban of the Laboratory for Photosynthetic Bacteria at the French National Center for Scientific Research. The objective of their research is to investigate the interaction between proton residues and quinones in reaction centers of photosynthetic bacteria. They will evaluate proton uptake and electron transfer. The U.S. investigator brings to this collaboration expertise in computation and theory. The calculations will be carried out at City College. This is complemented by French experimental expertise. Experimental measurements of the in situ electrochemistry and proton uptake will be made on wild type and mutant reaction centers. This combined theoretical and experimental effort will advance our understanding of electron transfer in photosynthetic systems and the structure of reaction centers to their function. These are important goals of photosynthesis research.
