Figure 4From: Protective versus pathogenic anti-CD4 immunity: insights from the study of natural resistance to HIV infectionLocal differences in the conformation of CD4 in the gp120-bound versus free state. Absolute variations of dihedral backbone angles Φ (upper panel) ad Ψ (lower panel) between bound and free CD4 structure are plotted on the y-axis against the single residues (on the x-axis) whose local geometry is influenced by the interaction between the two moieties.Back to article page
