Figure 4. The LuxO Inhibitor does not affect DNA binding.

LuxO D47E DNA binding in the presence and absence of compounds 11 and 12 was investigated by gel mobility shift assays (A) and fluorescent anisotropy assays (B). In (A), LuxO D47E was present at 1 µM. Compounds 11 and 12 were present at 200 µM. In (B), LuxO D47E was present at the indicated concentrations and compounds 11 and 12 were present at 200 µM. Error bars are present, but are too small to be observed in the plot. The bars represent standard errors of the mean for three independent trials.
