WebJan 21, 2024 · FtsZ is a widely-conserved, bacterial homolog of tubulin, it forms short and dynamic filaments that move around the middle of the cell. The filaments move via treadmilling, where new monomers are added to the growing end of polymer and removed from the shrinking end after GTP hydrolysis, in good analogy to actin. WebMar 22, 2024 · While treadmilling of FtsZ filaments has been discussed extensively as driving force of septum constriction (17, 34–38), several studies have shown that FtsZ GTPase and therefore treadmilling function become nonessential for cell division after assembly of the septal peptidoglycan synthase complex (7, 20, 25, 39) while still … WebJul 1, 2024 · We find that FtsZ treadmilling has two essential functions: mediating condensation of diffuse FtsZ filaments into a dense Z-ring, and initiating constriction by guiding septal cell wall synthesis. show10hotel queens drglasgow
