Figure 2.

Crystal structure of the VRC01 antibody-gp120 complex (PDB id: 5CD5) (A) and a fragment of gp120 with selected interacting residues of the antibody (B). gp120 is shown as a cyan ribbon or as a solvent-accessible surface colored by interpolated charge (blue–positive, gray–neutral, red–negative). The antibody is shown as violet or dark blue ribbons for the light and heavy chains, respectively. Interacting residues are shown in stick representation with carbon atoms colored the same as the parent chain. Intermolecular interactions are shown as dashed lines in the same color as in Figure 1.
