Figure 4.

Per-residue Kullback-Leibler divergence values for difference in sampled dihedral angles for the (a) L1-mutant, (b) macroH2A, and (c) H2A.Z nucleosomes, referenced against populations from the canonical system. The dimers and DNA residues are represented in a rainbow spectrum. Narrow and blue regions display similar dynamics to the canonical nucleosome, and regions displaying larger divergence values are wider and increase from blue to green to red. The tetramer is shown in magenta, where the tube radius is wider for residues with larger deviations from canonical-like dynamics. Divergence values are large near the L1-L1 interface (red circle), but significant differences are also observed in faraway regions. To see this figure in color, go online.
