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 ). WebSep 27, 2024 · The ring contains membrane-anchored cytokinetic nodes (inset), protein assemblies where eight Myo2 dimers and a formin Cdc12 dimer are attached to each other and to the node anchor that can slide along the membrane.

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.
