The aPBP-type cell wall synthase PBP1b plays a specialized role in fortifying the <i>Escherichia coli</i> division site against osmotic rupture.

A multi-protein system called the divisome promotes bacterial division. This apparatus synthesizes the peptidoglycan (PG) cell wall layer that forms the daughter cell poles and protects them from osmotic lysis. In the model Gram-negative bacterium <i>Escherichia coli</i> , PG synthases called class A penicillin-binding proteins (aPBPs) have been proposed to play crucial roles in division. However, there is limited experimental support for aPBPs playing a specialized role in division that is dist ...[more]
