Abstract
Bacterial photosynthetic membranes, also known as chromatophores, are tightly packed with integral membrane proteins that work together to carry out photosynthesis. Chromatophores display a wide range of cellular morphologies; spherical, tubular, and lamellar chromatophores have all been observed in different bacterial species, or with different protein constituents. Through recent computational modeling and simulation, it has been demonstrated that the light-harvesting complexes abundant in chromatophores induce local membrane curvature via multiple mechanisms. These protein complexes assemble to generate a global curvature and sculpt the chromatophores into various cellular-scale architectures.
摘要
细菌光合膜，也被称为类囊体，紧密排列着整合膜蛋白，共同完成光合作用。类囊体呈现出广泛的细胞形态；在不同的细菌物种中，或者在不同的蛋白质组成中，都观察到了球形、管状和层状的类囊体。通过最近的计算建模和模拟，已经证明类囊体中丰富的光捕获复合物通过多种机制诱导局部膜曲率。这些蛋白质复合物组装在一起产生全局曲率，并将类囊体塑造成各种细胞尺度的结构。
