Figure 4

Transmission electron micrographs of 13-induced filaments of (A) SaFtsZ and (B) EcFtsZ. Polymerization of the proteins was induced by addition of 20 μg/mL 13 under the experimental conditions described in the legend to Figure 3. The filaments were negatively stained with a solution of 1% phosphotungstic acid (PTA) and visualized at 80 kV on a Philips CM12 transmission microscope interfaced with an AMT XR111 camera. The red, white, and yellow arrows in panel A highlight filaments 5, 11, and 25 nm wide, respectively. The red arrow in panel B highlights a 5 nm wide filament.
