Figure 1.

On-dyad (top) and off-dyad (bottom) chromatosome structures. Global structures are shown on the left with zoomed-in figures of the linker histones GH1.0 (top) and genGH1 (bottom) are on the right. On the left, histones are color-coded as follows: Histone H2A (yellow), Histone H2B (red), Histone H3 (blue), Histone H4 (green), Histone genGH1/GH1.0 (purple) and DNA (gray). On the right the linker histones are colored by secondary structure: α-helix 1 (α1; red), α-helix 2 (α2; blue), α-helix 3 (α3; green), the β-sheet (yellow), and disordered regions (purple). Sequences for genGH1 and GH1.0 are shown on the bottom, with identical residues in green.
