Bacterial cell division
Even though we probably have a complete list of proteins involved in bacterial cell division, how these molecular players are able to self-organize into a functional machinery at the right place and time is not clear. In this research project, we are aiming to understand the mechanism of bacterial cytokinesis by reconstituting the Escherichia coli cell division machinery in a stepwise fashion.
Our goal is to understand the function of divisome proteins for the spatiotemporal organization and mechanics of the entire machinery.
Currently addressing the following questions regarding bacterial cell division:
- How do FtsZ associated proteins modulate the organization of FtsZ filaments?
- How do treadmilling FtsZ filaments organize cell division proteins in space and time?
