DNA helical parameters of complexes of CAP with DNA sites containing all possible base pairs at position 6 of the primary-kink site obtained in this study. The figure presents a plot of DNA roll angle versus DNA twist angle for each dinucleotide step of each half-complex herein (triangles, steps in half-complexes A; squares, steps in half-complexes B). DNA sequences are as in Figure 1. Colors are as in Figure 2.
