Fig. 2.

Intrinsic conformational preferences of WT (blue) and LYS-16 AC (blue) H4 tails are shown using their P(q) distributions. The small peak on the right side shows the emergence of more structured and also slightly more compact states in the conformational ensemble of the AC H4 tail. The inset shows how the percentages of structures with the secondary structural elements are affected by the acetylation of LYS-16. Secondary structures were estimated based on the DSSP algorithm, where only structures with more than four residues in either alpha or beta conformations were considered.
