Fig. 3From: Development of an HIV vaccine using a vesicular stomatitis virus vector expressing designer HIV-1 envelope glycoproteins to enhance humoral responses(This model was adapted from [35])Schematic of gp120 HIV-1YU-2 complexed with CD4 and 412 Ab (PDB ID: 2QAD) [38] and modeled using the COOT program to contain the N425 to K mutation in gp120. The Nε of K425 can interact with residues from CD4 including a cation-π interaction with F43 of CD4Back to article page
