Lay Summary (English)

Lay summary
FtsZ is the prokaryotic homolog of tubulin. This GTPase is essential for bacterial cell division and is widely conserved in bacteria. However, FtsZ is absent in mammalian cells which makes it an attractive broad-spectrum antibacterial target. The goal of the project is the characterization of structural and dynamic properties of FtsZ. In this study we want to find the structural basis for the correlation between two related aspects of the function of FtsZ, namely the GTPase activity and the polymerization process. For a better understanding of the mechanism underlying the GTPase activity, we will investigate the conformation and dynamic properties in the Apo form of FtsZ and compare it with the complex with GDP and non-hydrolyzable analogous of GTP. For the latter studies non-polymerizing variants of FtsZ will be used. The structural characterization by NMR will be further facilitated by the availability of independently folding subdomains of FtsZ. Understanding the structural basis of the functions of FtsZ will support the rational design of novel compounds that may be used as antibiotics. Based on our results Prof. Monasterio (University of Chile, Santiago) will perform in-vivo studies with variants of FtsZ which in turn will raise new questions about their structural and dynamic properties.
