Structural Basis for Species Selectivity in the HIV-1 gp120-CD4 Interaction: Restoring Affinity to gp120 in Murine CD4 Mimetic Peptides

Figure 6

Fluctuations of torsion angles in loops flanking strand C″ of mCD4-M. (a) Schematic presentation of the mCD4-M peptide topology. Analyzed loops are colored red. (b) Dihedral angles of the loops flanking strand C″ as function of simulation time are shown in the left and right column, respectively. φ angle (C_i-1-N_i-C_i ^α-C_i) and ψ angle (N_i-C_i ^α-C_i-N_i+1) are colored in black and gray, respectively.
