Lacking fragments reconstructed by the program CORAL are shown as spheres. Bottom: The best CORAL model using the minor A2 site (site #2) of A2:H2A/H2B complex as a starting structure (See Figure 5D in the primary citation). Lacking fragments reconstructed by the program CORAL are shown as spheres.
