Color-coded histograms illustrating sequence-dependent features of DNA found in high-resolution protein–DNA structures of specified resolution accumulated as of February 2022: (a) number of base-pair steps; (b) intrinsic dimer structure measured in terms of the average twist angle $\langle {\theta }_3\rangle$ between successive base pairs; (c) dimer deformability measured in terms the average volume of configuration space $\langle V_{\mathrm{step}}\rangle$ accessed by individual steps. See Table S3 for numerical values.
