Abstract
Bacteria use homologs of eukaryotic cytoskeletal filaments to conduct many different tasks, controlling cell shape, division, and DNA segregation. These filaments, combined with factors that regulate their polymerization, create emergent self-organizing machines. Here, we summarize the current understanding of the assembly of these polymers and their spatial regulation by accessory factors, framing them in the context of being dynamical systems. We highlight how comparing the in vivo dynamics of the filaments with those measured in vitro has provided insight into the regulation, emergent behavior, and cellular functions of these polymeric systems.
摘要
细菌利用真核细胞细胞骨架丝的同源物来执行许多不同的任务，控制细胞形状、分裂和DNA分离。这些细丝与调节其聚合的因子相结合，形成了新兴的自组织机器。在这里，我们总结了目前对这些聚合物组装及其由辅助因子进行的空间调节的理解，并将它们置于动态系统的背景下。我们强调了将细丝在体内的动力学与体外测量的动力学进行比较，如何为这些聚合物系统的调节、新兴行为和细胞功能提供了见解。
