The photosynthetic pigments of chloroplast thylakoid membranes are complexed with specific intrinsic polypeptides which are included in three supramolecular complexes, photosystem I complex, photosystem II complex and the light-harvesting complex. There is marked lateral heterogeneity in the distribution of these complexes along the membrane with photosystem II complex and its associated light-harvesting complex being located mainly in the stacked membranes of the grana partitions, while photosystem I complex is found mainly in unstacked thylakoids together with ATP synthetase. In contrast, the intermediate electron transport complex, the cylochrome b-f complex, is rather uniformly distributed in these two membrane regions. The consequences of this lateral heterogeneity in the location of the thylakoid complexes are considered in relation to the function and structure of chloroplasts of higher plants.
叶绿体类囊体膜的光合色素与特定的内在多肽复合，这些多肽包含在三个超分子复合物中，即光系统I复合物、光系统II复合物和捕光复合物。这些复合物沿膜的分布存在明显的横向异质性，光系统II复合物及其相关的捕光复合物主要位于基粒分区的堆叠膜中，而光系统I复合物主要存在于未堆叠的类囊体中，与ATP合成酶在一起。相比之下，中间电子传递复合物，即细胞色素b-f复合物，在这两个膜区域中分布较为均匀。本文结合高等植物叶绿体的功能和结构，探讨了类囊体复合物位置的这种横向异质性的影响。
