Figure 7

Structure prediction accuracy for the H3 designs versus surface accessibility. Backbone RMSD of the H3 loop between predicted designs and their crystal structures is highlighted by color ranges. Surface Accessibility as defined in MOE (Chemical Computing Group) is calculated using the crystal structure and is shown under each corresponding H3 loop sequence as histograms indicating the degree of burial. Positive bars indicate that a residue is buried. Dashed purple rectangles highlight H3 stem regions.
