Figure 6: The Sir3 BAH domain binds nucleosomes but does not coat or occlude linker DNA.
From: Solution-state conformation and stoichiometry of yeast Sir3 heterochromatin fibres

(a) AFM images and height measurements of WT and H4-K16Q arrays bound by the Sir3 BAH domain. The mean heights and 95% confidence intervals are shown above the height histograms. (b) Representative, detailed 3D and 3D images of WT and H4-K16Q arrays in the presence of the Sir3 BAH domain in both 2D and 3D.
