Photosynthesis consists of a series of endergonic redox reactions, with light as the source of energy, chlorophyll as the energy converter, and electrons flowing through membrane and soluble proteins. Here, we give an account of the most recent results on the structure-function relationships of the membrane-embedded complexes cytochrome b(6)-f and photosystem I and of the two soluble proteins (cytochrome c(6) and plastocyanin) that serve as alternative electron carriers between them. Particular attention is paid to the evolutionary aspects of the reaction mechanism and transient protein-protein interactions between the membrane complexes and their partners in cyanobacteria, eukaryotic algae, and plants.
光合作用由一系列吸能的氧化还原反应组成，以光为能量来源，叶绿素为能量转换器，电子流经膜蛋白和可溶性蛋白。在此，我们阐述了关于膜嵌入复合物细胞色素b(6)-f和光系统I以及两种可溶性蛋白（细胞色素c(6)和质体蓝素）结构-功能关系的最新研究结果，这两种可溶性蛋白在它们之间作为替代电子载体。特别关注了蓝细菌、真核藻类和植物中反应机制的进化方面以及膜复合物与其伙伴之间的瞬时蛋白质-蛋白质相互作用。
