  光合膜蛋白复合物结构及功能

  光合作用是地球上最重要的化学反应之一。蓝细菌、藻类和高等植物等放氧光合生物在利用太阳能将二氧化碳转变为有机物的同时,还能释放出氧气,为地球上几乎所有生物体提供赖以生存的物质和能量。放氧光合生物都有两个光系统,分别是光系统I和光系统II,它们都由反应中心和捕光天线组成。捕光天线负责吸收太阳光能并传递到反应中心,在反应中心发生电荷分离和水裂解反应,释放氧气。光合生物为了适应不断变化的自然环境,进化出一系列的调控机制,包括非化学能量淬灭、状态转换和环式电子传递等。我们主要利用结构生物学手段,综合运用X-射线晶体学和冷冻电子显微镜技术来研究光合作用相关的膜蛋白复合体的结构及功能,揭示光合生物进行光能捕光、能量传递、光保护、状态转换和环式电子传递等一系列重要过程的分子机理及调控机制。目前的主要研究进展包括:

  1. 揭示了蓝藻环式电子传递过程的分子机理(Nat Commun,2020)。

  2. 解析了绿藻光系统I复杂的天线系统结构及色素网络,揭示了其高效捕光和能量传递的分子机理(Nat Plants,2019)。

  3. 阐明了在不断变换的自然光环境中,高等植物两个光系统进行能量平衡分配的状态转换机制(Science,2018; BBA Bioenerg, 2020)。

  4. 揭示了高等植物光系统II捕光天线CP29捕光和能量传递的分子机制,发现了其潜在的能量淬灭中心(Nat Struct Mol Biol, 2011; Curr Opin Struct Biol, 2013)。
