Assembly of the tubulin-like protein FtsZ at or near the cytoplasmic membrane is one of the earliest steps in division of bacteria such as Escherichia coli. Exactly what constitutes the site at which FtsZ acts is less clear. To investigate the influence of the membrane phospholipids on FtsZ localization and assembly, we have elaborated with the Langmuir technique a two-lipid monolayer made of dilauryl-phosphatidylethanolamine...
The positioning of the site of cell division in Escherichia coli results, it is generally believed, from the operation of nucleoid occlusion in combination with the Min system. Nucleoid occlusion prevents division over the nucleoids and directs it by default to the mid-cell region between segregating nucleoids or to polar regions while the Min system prevents division in polar regions. Unresolved...
