WebOct 17, 2011 · Cytokinesis in Escherichia coli and other bacteria is mediated by a ring-shaped multiprotein machine called the “septal ring” or “divisome” ( 1 ). Assembly of this machine begins with the polymerization of the tubulin-like FtsZ protein into a ring-like structure just underneath the cell membrane at the prospective site of division ( 2 ). WebHowever, destruction of the cytokinetic Z-ring indicates that at thesamedose, ithinders bacterial cytokinesis bydisrupting the development and function of the Z-ring.

WebJan 23, 2024 · Constriction of the actin cytokinetic ring is an essential step of cell division. In a generally accepted view, the constriction is driven by relative sliding of actin filaments propelled by myosin motors. However, in multiple organisms, the ring constriction is myosin independent. How actin rings constrict in the absence of motor activity remains unclear.
