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.

WebFeb 4, 2024 · Biochemical work demonstrates that FtsZ filaments move directionally by a treadmilling mechanism, similar to that first found for eukaryotic tubulins ().In treadmilling, FtsZ-GTP monomers add to the growing (+) end of advancing filaments, and FtsZ-GDP, produced by FtsZ-catalyzed GTP hydrolysis, dissociate from the other disappearing (−) … WebFeb 17, 2024 · Our results show that FtsZ engages in treadmilling powered by GTP hydrolysis to spatially organize the septal PG synthesis machinery without limiting the rate of septum closure. In Bacillus subtilis, FtsZ treadmilling appears to distribute septal PG synthesis and also to dictate the synthesis rate . The differences between the two …
