A Multistranded Polymer Model Explains MinDE Dynamics in E. coli Cell Division

From: Biophysical Journal | Date: August 15, 2007| Author: | Copyright information

ABSTRACT

In Escherichia coli, the location of the site for cell division is regulated by the action of the Min proteins. These proteins undergo a periodic pole-to-pole oscillation that involves polymerization and ATPase activity of MinD under the controlling influence of MinE. This oscilla tion suppresses division near the poles while permitting division at midcell. Here, we propose a multistranded polymer model for MinD and MinE dynamics that quantitatively agrees with the experimentally observed dynamics in wild-type cells and in several well-studied mutant phenotypes. The model also ...
