Figure 5. DNA recognition by CT-Ler is dictated by the minor groove width.

Figure 5

(A) Stick representation of Arg90 side chain inserted at the floor of the negatively charged LeeH minor groove. The electrostatic potential of LeeH, calculated in the absence of CT-Ler, is plotted on the LeeH surface. (B) Average minor-groove width (blue) and electrostatic potential in the centre of LeeH minor groove (red). The position of the guanidium group of Arg90 is indicated. (C-D) Helical parameters of LeeH in complex with CT-Ler. Roll and helix twist angles are shown. Dashed lines correspond to values typical of canonical B-DNA [56].
