US-France Cooperative Research Investigation of the Role of the Iron Metal in the Interquinone Electron Transfer in Bacterial Reaction Centers

0233310枪手这两年的美国奖-法国在光合作用方面的合作研究涉及纽约城市大学城市学院的Marilyn Gunner和研究生以及法国国家科学研究中心（CNRS）分子遗传学中心的Pierre Sebban和他的学生。 目的是确定蛋白质结构和电子传递的光合反应中心的紫色细菌。 这些细菌允许光激活，单周转测量。 研究人员建议确定蛋白质中特定分子变化的障碍。 法国研究小组将构建反应中心突变体，用于研究决定醌A和醌B之间电子转移的分子基础。 美国团队将负责低温实验和其他测量。该奖项代表了美国方面向NSF和法国国家科学研究中心（CNRS）提出的联合提案。 NSF将支付美国研究员的旅费和生活费，以及两名美国研究生的研究访问费用。 CNRS将支持法国研究人员访问美国。

0233310GunnerThis two-year award for U.S.-France cooperative research in photosynthesis involves Marilyn Gunner and graduate students at City College of the City University of New York and Pierre Sebban and his students at the Center for Molecular Genetics of the French National Center for Scientific Research (CNRS). The objective is to determine protein structure and electron transfer in the photosynthetic reaction centers of purple bacteria. These bacteria allow light-activated, single turn-over measurements. The investigators propose to determine barriers to specific molecular changes in the protein. The French team will construct reaction center mutants for study of the molecular basis for determining in electron transfer between quinone A and quinone B. The US team will be in charge of low temperature experiments and other measurements. This award represents the U.S. side of a joint proposal to the NSF and the French National Center for Scientific Research (CNRS). NSF will cover travel funds and living expenses for the U.S. investigator and research visits for two U.S. graduate students. The CNRS will support the visits of the French researchers to the United States.
