Figure 5

Scheme for the mechanism of open rings and cylinders formation induced by dNAK 4. Schematic representation of dNAK 4 effect on BsFtsZ polymerization. The filaments induced by GTP to explain the mechanism of inhibition of the polymerization of BsFtsZ produced by dNAK 4 is included. BsFtsZ-GDP form is indicated with gray spheres and the BsFtsZ-GTP form with black spheres. The scheme shows cylinder formation induced by GDP and the loss of protein suitable for filament formation, due to “sequestration” into the cylinders and their precursors.
