FIG. 8.

Validation of vaccine 3D model using Ramachandran plot. The Ramachandran plots of (a) the unrefined model and (b) the refined model. The most-favored (A, B, and L) and additional allowed (a, b, l, and p) regions were demonstrated with charcoal and silver gray colors, respectively. The generously allowed regions (∼a, ∼b, ∼l, and ∼p) are indicated in silver, and the disallowed regions are in white color. Glycine residues are shown in black triangles, and other residues of protein are shown in black squares.
