DNA structure and H-SASA profiles in the highest resolution X-ray structure of NCP (NCP147). (A) Local DNA rotational periodicity in nucleosome calculated from relative twist (rTw). (B) rTw of nucleosomal DNA along the sequence, plotted in 5′-3′ direction of the top strand (TS). (C) H-SASA profiles for TS (magenta) and bottom strand (cyan), both profiles and sequences beneath are given in 5′-3′ direction. The H-SASA profiles calculated from MD trajectory of NCP147 without histone tails (see ‘Materials and Methods’ section).
