Figure 5

A. Determination of IC50 values for hits in the presence of 1 unit (50 nM) of M. mazei topo VI. This resulted in the following IC50 values: 6 μM for 9-aminoacridne; 30 μM for m-amsacrine; 30 μM for suramin; 30 μM for hexylresorcinol; 40 μM for purpurin; 8 μM for quinacrine; and 2 μM for mitoxanthrone. B. Native gel shift assays for the binding of M. mazei topo VI to a 147 bp DNA fragment in the presence of screen hits.
