FtsN maintains active septal cell wall synthesis by forming a processive complex with the septum-specific peptidoglycan synthases in E. coli

Z Lyu, A Yahashiri, X Yang, JW McCausland… - Nature …, 2022 - nature.com
FtsN plays an essential role in promoting the inward synthesis of septal peptidoglycan (sPG)
by the FtsWI complex during bacterial cell division. How it achieves this role is unclear. Here …

In vitro reconstitution of Escherichia coli divisome activation

P Radler, N Baranova, P Caldas, C Sommer… - nature …, 2022 - nature.com
The actin-homologue FtsA is essential for E. coli cell division, as it links FtsZ filaments in the
Z-ring to transmembrane proteins. FtsA is thought to initiate cell constriction by switching …

Cell cycle-dependent recruitment of FtsN to the divisome in Escherichia coli

J Männik, S Pichoff, J Lutkenhaus, J Männik - Mbio, 2022 - Am Soc Microbiol
Cell division in Escherichia coli starts with the formation of an FtsZ protofilament network at
midcell, the Z ring. However, only after a considerable lag period does the cell start to form a …

Self-organisation of mortal filaments: the role of FtsZ treadmilling in bacterial division ring formation

C Vanhille-Campos, KD Whitley, P Radler, M Loose… - bioRxiv, 2023 - biorxiv.org
Functional protein filaments in the cell commonly treadmill–grow and shrink on opposite
ends, driven by energy consumption. Treadmilling causes filaments to seem as if they were …

Cytomotive actins and tubulins share a polymerisation switch mechanism conferring robust dynamics

JM Wagstaff, VJ Planelles-Herrero, G Sharov, A Alnami… - bioRxiv, 2022 - biorxiv.org
Protein filaments are used in myriads of ways to organise other molecules in space and time
within cells. Some filament-forming proteins couple the hydrolysis of nucleotides to their …
