FIG 6.

FtsZ ring localization and cell division is inhibited by ADG. ADG and ciprofloxacin inhibit localization of FtsZ at the division site. E. coli MG1655 FtsZ-GFP was grown and treated with either ADG (128 μg/mL), ciprofloxacin (1 μg/mL), cephalexin (8 μg/mL), or no drug for 1 h at 37°C. Cells were spotted onto a 1.5% low-melting-point agarose pad and observed with a fluorescence microscope. This experiment was repeated three times. This image is a representative of three independent experiments.
