9603300 Okamura This award supports a two year collaborative research project between Professor Melvin Okamura of the University of California at San Diego and Dr. Teizo Kitagawa of the Okazaki National Research Institute in Japan. This project undertakes a study of the elucidation of a coupling mechanism of electron and proton transfers at the quinone-B site of photosynthetic reaction centers by using resonance Raman spectroscopy. The major goals of this project are: 1) investigate the structure and function of photosynthetic reaction centers; 2) determine the role of quinone-B in electron and proton transfer; and 3) apply resonance Raman studies to quinones in bacterial reaction centers. The project brings together the efforts of two laboratories that have constituted different parts of the process: the Americans have expertise in the preparation and characterization of reaction centers and the Japanese laboratory has the facilities for extensive experience in biological application of resonance Raman spectroscopy. Through the exchange of ideas and technology, this project will broaden our base of basic knowledge and promote international understanding and cooperation. ***

小行星9603300 该奖项支持加州大学圣地亚哥分校的Melvin Okamura教授和日本冈崎国立研究所的Teizo Kitagawa博士之间为期两年的合作研究项目。 本项目利用共振拉曼光谱技术，对光合作用反应中心醌B位的电子和质子转移的耦合机制进行了研究。 本计画的主要目的为：1）研究光合反应中心的结构与功能; 2）确定醌-B在电子与质子传递中的角色; 3）应用共振拉曼研究细菌反应中心中的醌。 该项目汇集了两个实验室的努力，这两个实验室构成了该过程的不同部分：美国人在反应中心的制备和表征方面具有专业知识，日本实验室在共振拉曼光谱的生物应用方面具有丰富的经验。 通过交流思想和技术，该项目将扩大我们的基础知识，促进国际理解与合作。 ***
