Figure 3

DNA structure in the R.PabI-nonspecific dsDNA complex.
(a) The structure of dsDNA between the two R.PabI dimers. R.PabI and DNA are colored in the same way as Fig. 1. DNA axis is shown as a blue line. (b) Plots of major (blue line) and minor (red line) groove width as a function of DNA sequence. The major and minor groove widths of ideal B-form dsDNA are shown as purple and green dotted lines, respectively.
