The stoichiometric divisome: a hypothesis
Dividing Escherichia coli cells simultaneously constrict the inner membrane, peptidoglycan layer, and outer membrane to synthesize the new poles of the daughter cells. For this, more than 30 proteins localize to mid-cell where they form a large, ring-like assembly, the divisome, facilitating division. Although the precise function of most divisome proteins is unknown, it became apparent in rece...
متن کاملDo the divisome and elongasome share a common evolutionary past?
The divisome and elongasome are bacterial protein complexes responsible for peptidoglycan (PG) synthesis during cell division and elongation, respectively. We review several lines of evidence, arguing for a shared evolutionary past of the divisome and elongasome. Both integrate closely related penicillin-binding proteins (PBPs) for PG synthesis, use proteins of the RodA/FtsW (SEDS, shape, elong...
متن کاملThe divisome at 25: the road ahead.
The identification of the FtsZ ring by Bi and Lutkenhaus in 1991 was a defining moment for the field of bacterial cell division. Not only did the presence of the FtsZ ring provide fodder for the next 25 years of research, the application of a then cutting-edge approach-immunogold labeling of bacterial cells-inspired other investigators to apply similarly state-of-the-art technologies in their o...

متن کاملSolution structure and domain architecture of the divisome protein FtsN.
Prokaryotic cell division occurs through the formation of a septum, which in Escherichia coli requires coordination of the invagination of the inner membrane, biosynthesis of peptidoglycan and constriction of the outer membrane. FtsN is an essential cell division protein and forms part of the divisome, a putative complex of proteins located in the cytoplasmic membrane. Structural analyses of Ft...
