CP footprinting of ToxT on spacing variants. Experiments were performed using histidine-tagged ToxT and purified end-labeled DNA as described in Materials and Methods. Lanes G, A, T, and C are the sequencing reaction lanes used for size markers, lane F contained free DNA, and lane B contained DNA complexed with ToxT. The numbers indicate the positions of inserted or deleted DNA sequence. (A) CP footprinting for the acfD +5t construct. (B) CP footprinting for the acfD −2t construct. (C) CP footprinting for the tagA +3t construct. (D) CP footprinting for the tcpA +4t construct.
