FtsA is thought to initiate cell constriction by switching from an inactive polymeric to an active monomeric conformation, which recruits downstream proteins and stabilizes the Z-ring. However, direct biochemical evidence for this mechanism is missing. Here, we use reconstitution experiments and quantitative fluorescence microscopy to study divisome activation in vitro. By comparing wild-type FtsA with FtsA R286W, we find that this hyperactive mutant outperforms FtsA WT in replicating FtsZ treadmilling dynamics, FtsZ filament stabilization and recruitment of FtsN. We could attribute these differences to a faster exchange and denser packing of FtsA R286W below FtsZ filaments. Using FRET microscopy, we also find that FtsN binding promotes FtsA self-interaction. We propose that in the active divisome FtsA and FtsN exist as a dynamic copolymer that follows treadmilling filaments of FtsZ.","lang":"eng"}],"volume":13,"date_created":"2022-05-13T09:06:28Z","publisher":"Springer Nature","day":"12","department":[{"_id":"MaLo"}],"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","isi":1,"article_processing_charge":"No","acknowledged_ssus":[{"_id":"Bio"},{"_id":"LifeSc"}],"file":[{"file_size":6945191,"relation":"main_file","date_updated":"2022-05-13T09:10:51Z","success":1,"content_type":"application/pdf","file_name":"2022_NatureCommunications_Radler.pdf","file_id":"11374","creator":"dernst","checksum":"5af863ee1b95a0710f6ee864d68dc7a6","access_level":"open_access","date_created":"2022-05-13T09:10:51Z"}]}
