WebApr 24, 2024 · Two new studies report that FtsZ polymers move around the ring by treadmilling, which guides and regulates the inward growth of the septal wall. Breaking up is hard to do and, even for relatively simple bacteria, cytokinesis is arguably the most difficult single mechanical challenge that a cell faces. WebAbstract. Most bacteria assemble a ring-like macromolecular machinery scaffolded by the essential cytoskeletal protein FtsZ for cell division. Studies have broadly explored how FtsZ could polymerize at the correct place and time. Recently, the FtsZ-ring was found to exhibit dynamic treadmilling along the circumference of the division site ...

WebMay 18, 2024 · Author summary FtsZ is a tubulin homologue and the primary protein of the bacterial Z ring that guides cell division. In vivo, but also in reconstituted systems, FtsZ shows an intriguing treadmilling dynamic along circular tracks of approximately 1 micrometer in diameter. In cells, this treadmilling along the circumference of the division … WebFeb 17, 2024 · We found that in Escherichia coli cells, FtsZ exhibits dynamic treadmilling predominantly determined by its guanosine triphosphatase activity. The treadmilling dynamics direct the processive movement of the septal cell wall synthesis machinery but do not limit the rate of septal synthesis.
