Figure 1

Structural parameters calculated from averaged DNA coordinates by Curves 5.2 (51). Regions of the points are marked as follows: K/20, light green circles; K/15, green circles; Na/20, light red squares; Na/15, red squares; M/20 and M/15 systems are shown as closed and open symbols, respectively. Parameters were paired according to Ref. (74); the blue and purple ovals show regions typical for B- and A-DNA families, respectively, found from analysis of X-ray crystallography data. (More information is available in Supplementary Data where Supplementary Figure 2S displays the values shown in this figure in dependence of the DNA sequence).
