Figure 3. Structural fluctuations in the nucleosome.
(A) Temperature factor of the nucleosome in cartoon representation. The atoms are colored as indicated in the scale. (B) Secondary structure of the histone calculated using the dssp program [45]. During the simulation amino acids 14–20 of H3 (copy 1) and amino acids 11–15 of H2B (copy 1) show propensity to form -helices.
