A mechanistic stochastic framework for regulating bacterial cell division
How exponentially growing cells maintain size homeostasis is an important fundamental problem. Recent single-cell studies in prokaryotes have uncovered the adder principle, where cells add a fixed size (volume) from birth to division, irrespective of their size at birth. To mechanistically explain the adder principle, we consider a timekeeper protein that begins to get stochastically expressed ...
متن کاملBacterial Cell Division: A Swirling Ring to Rule Them All?
FtsZ, a tubulin homologue and the major constituent of the bacterial Z ring, has been shown to assemble into curved filament bundles, which exhibit GTP-hydrolysis-dependent turnover. Surprisingly, the presence of its membrane adaptor FtsA renders this turnover directional, inducing treadmilling and collective circular motion of filaments in vitro.

متن کاملBacterial Division: The Fellowship of The Ring
The Z ring, composed of the tubulin homolog FtsZ, is essential for bacterial cell division. Recently a new protein, ZapA, has been discovered that localizes to the Z ring and stabilizes it, probably by promoting the bundling of FtsZ protofilaments.
