Division of Bacterial Infection

Liposome division by a simple bacterial division machinery.

We previously reconstituted Z rings in tubular multilamellar liposomes with FtsZ-YFP-mts, where mts is a membrane-targeting amphiphilic helix. These reconstituted Z rings generated a constriction force but did not divide the thick-walled liposomes. Here we developed a unique system to observe Z rings in unilamellar liposomes. FtsZ-YFP-mts incorporated inside large, unilamellar liposomes formed ...

Targeting the Bacterial Division Protein FtsZ.

Similar to its eukaryotic counterpart, the prokaryotic cytoskeleton is essential for the structural and mechanical properties of bacterial cells. The essential protein FtsZ is a central player in the cytoskeletal family, forms a cytokinetic ring at mid-cell, and recruits the division machinery to orchestrate cell division. Cells depleted of or lacking functional FtsZ do not divide and grow into...

Bacterial division: Finding the dividing line

Division of a cell - whether eukaryotic or prokaryotic - requires accurate spatial coordination. Recent work on the bacterium Escherichia coli has shown that correct placement of the cell division site at the midcell position occurs by a combination of selection against potential polar sites and selection of the midcell site.
