Fig. 8. Histograms of DNA bend angles induced by E. coli and Taq MutS on full homoduplex DNA substrates. DNA bend angles for E. coli MutS bound to DNA fragments made from restriction enzyme-digested pUC18 plasmid (a), for Taq MutS bound to 782Homo DNA substrate at room temperature (b), for Taq MutS bound to restriction enzyme-digested pUC18 plasmid at room temperature (c), and for Taq MutS bound to 782Homo DNA substrate at 65ºC (d). The curves drawn in the plots are the single Gaussian fits to the data. The statistical analysis results are shown in Table 1.
