叶绿体类囊体腔蛋白功能研究进展

【目的】类囊体是叶绿体光合作用中光反应进行的重要场所。类囊体腔是由类囊体膜包围形成的一个狭小空间。在类囊体腔中存在多种不同的蛋白家族，包括高叶绿素荧光(high chlorophyll fluorescence, HCF)蛋白、亲免蛋白、放氧复合物(oxygen-evolving complex, OEC)蛋白、PsbP类蛋白等，它们对植物的光合作用、核酸代谢以及氧化还原反应等都起着重要作用。【评论】文章分类综述了参与光合作用调控的类囊体腔蛋白在光系统组装、植物生长发育调节和高光逆境响应等生理活动中发挥的重要作用。【展望】文章可为未来研究类囊体腔蛋白的生理功能提供理论参考。

Research advance on the function of chloroplast thylakoid lumen proteins

Thylakoids are the important sites where photosynthesis takes place. The thylakoid membrane envelops a central aqueous region known as the thylakoid lumen. There are various types of proteins residing in thylakoid lumen including high chlorophyll fluorescence (HCF) protein, immunophilins, oxygen-evolving complex (OEC) proteins, PsbP-like proteins, etc. These proteins were considered to play important roles during various physiological processes, such as photosynthesis, nucleotide metabolism and redox regulation. This review systematically summarizes the function of thylakoid lumen proteins involved in photosynthesis regulation, such as photosystem assembly, growth regulation and excess light stress response, and provides the theoretical reference for future study on the physiological function of thylakoid lumen proteins.
