标题： Min-oscillations in Escherichia coli induced by interactions of membrane-bound proteins

摘要： 在分裂过程中，细胞正确确定分裂部位是至关重要的。 细菌大肠杆菌在中心分裂，产生两个大小相等的子细胞。 选择中心作为正确的分裂部位部分是通过Min蛋白实现的。 它们在两个细胞极之间振荡，从而防止在这些位置发生分裂。 在这里，提出了这些振荡的表征描述，其中细胞膜上蛋白质之间的侧向相互作用起着关键作用。 动态方程的解与实验结果进行比较。 特别是，振荡的时间周期被测量为细胞长度的函数，并发现与理论预测相容。 显示英文摘要

摘要： During division it is of primary importance for a cell to correctly determine the site of cleavage. The bacterium Escherichia coli divides in the center, producing two daughter cells of equal size. Selection of the center as the correct division site is in part achieved by the Min-proteins. They oscillate between the two cell poles and thereby prevent division at these locations. Here, a phenomenological description for these oscillations is presented, where lateral interactions between proteins on the cell membrane play a key role. Solutions to the dynamic equations are compared to experimental findings. In particular, the temporal period of the oscillations is measured as a function of the cell length and found to be compatible with the theoretical prediction.
