Proteins of the Photosynthetic Apparatus

本项目研究了质体青素与细胞色素f的相互作用以及细胞色素f与Rieske铁硫蛋白的相互作用，以了解相互作用域和电子通过这些蛋白质的路径。将研究细胞色素c550在蓝藻和藻类中的功能，以了解该蛋白的催化作用。蓝藻中一类特殊类胡萝卜素蛋白的合成和结构将被研究。盐生蓝藻的蛋白质结构将被研究，以了解蛋白质和膜结构对极高盐浓度的适应。这个项目支持对参与光合作用能量转换的蛋白质结构的研究。目的是更好地定义这些蛋白质的结构和相互作用。蓝藻将成为研究的主要对象，因为它们具有独特的实验优势。在大多数方面，蓝藻与其他氧气进化藻类和高等植物非常相似。它们很容易生长，特别适合重组DNA实验。它们的简单性为理解所有植物的光合作用过程提供了有利条件。它们的悠久历史和对恶劣环境的特殊适应为理解光合机构的进化提供了有利条件

This project investigates the interaction of plastocyanin with cytochrome f and the interaction of cytochrome f with the Rieske iron sulfur protein to learn the interacting domains and the path of electrons through these proteins. The function of cytochrome c550 in cyanobacteria and algae will be studied to learn the catalytic role of this protein. The synthesis and structure of a special class of carotenoid proteins in cyanobacteria will be examined. The structures of proteins in a halophytic cyanobacterium will be investigated to understand the adaptation of protein and membrane structures to extremely high salt concentrations.%%% This project supports a study of the structure of proteins which participate in photosynthetic energy conversion. The objective is to better define the structures of and the interactions between these proteins. Cyanobacteria will be the main objects of study since they afford unique experimental advantages. Cyanobacteria are, in most respects, very similar to other O2 evolving algae and higher plants. They are easily grown and are especially well suited for recombinant DNA experiments. Their simplicity provides advantages to the understanding of photosynthetic processes in all plants. Their long history and special adaptations to harsh environments provide advantages for understanding the evolution of the photosynthetic apparatus.***//
