FtsZ induces membrane deformations via torsional stress upon GTP hydrolysis

Abstract

During bacterial cell division, the protein FtsZ is the main component of the contractile ring, though how precisely FtsZ treadmilling and its ability to deform membranes cooperate are unclear. Here, the authors show that dynamic FtsZ may deform lipid membranes via torsional stress that may provide sufficient force to constrict membranes in vivo and in vitro.
