A, 3DVA of the nucleosomes containing linker DNAs. Five
representative structures (motion frames 3, 7, 11, 15, 19) from 3DVA component 1
class (total 20 frames) are shown. The structures of motion frames 3 and 19 were
selected and overlayed for each nucleosome. EM densities for the H2A C-terminal
region (orange arrows) and H1.8 (red arrows) are shown. See Movie S1 for full dataset. The
identical contour level was applied for maps in each data series.
B,
C, NCP structural variation of GUB-open nucleosomes (B) and
chromosomal nucleosomes (C).
