摘要
[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.
Abstract
[Objective]Thylakoids are the important sites where photosynthesis takes place.The thylakoid membrane envelops form a central aqueous region known as the thylakoid lumen.There are various types of proteins residing in thylakoid lumen,including high chlorophyll fluorescence(HCF)proteins,immu-nophilins,oxygen-evolving complex(OEC)proteins,and PsbP-like proteins,etc.These proteins are con-sidered to play important roles during various physiological processes,such as photosynthesis,nucleotide metabolism,and redox regulation.[Reviews]This review summarized the function of the thylakoid lumen proteins involved in photosynthesis regulation,such as photosystem assembly,growth regulation,and ex-cess light stress response.[Prospect]The review provided the theoretical reference for future study on the physiological function of the thylakoid lumen proteins.
