1 Introduction
In Escherichia coli and other rod-shaped bacteria, cell division
depends on the precise placement of a division septum
at the middle of the cell, a process initiated by the
assembly of an equatorial ring (Z-ring) of tubulin-like FtsZ
GTPase on the cytoplasmic membrane [1,2]. The Z-ring
assembly is spatially restricted to the mid-cell by nucleoid
occlusion [3,4] and by the dynamics of the Min system
[4–6]. The Min system consists of MinC, MinD, and MinE
expressed from the minB operon [5] which restricts separation
to the desired potential division site at mid-cell
through the oscillatory cycle from pole to pole (review
Ref. [7]).
