Figure 2. Distribution of tetranucleotide sequences according to average minor groove width.

Figure 2

Tetranucleotides from structures with a minimum length of one helical turn for which minor groove width can be defined are ordered by average minor groove width (red). The widths of all tetranucleotides are shown (black) and the sequence, average width, and occurrence in our dataset are given in Supplementary Table 2. (a) The 59 unique tetranucleotides from free DNA structures. (b) The set of all 136 unique tetranucleotides derived from protein-DNA complexes.
