摘要
叶绿体的空间结构有6个区隔:外膜、膜间隙、内膜、基质、类囊体膜和类囊体腔。重点介绍了运输蛋白的跨外膜转运和跨内膜转运的运输机制,分别在叶绿体外膜易位子TOC和内膜易位子TIC的协助下实现跨膜转运。同时,介绍了分子伴侣的作用,它可提供前体蛋白运输的动力。
The spatial structure of chloroplast was consisted of 6 regions：outer membrane,intermembrane space,inner membrane,matrix,thylakoid membrane and thylakoid lumen.The transportation mechanism of chloroplast protein across outer membrane and inner membrane were emphasized.The chloroplast transfer protein was transported across membrane with the assistance of translocation complex TOC and TIC.The role of chaperones in chloroplast protein import was also discussed.It could provide motive for preprotein transportation of chloroplast.
