Model for a full-length HIV-1JRFL gp120 in a CD4-bound state. (A) Full-length gp120 monomer model. Molecular model for a soluble CD4-bound full-length gp120 monomer was constructed as described in section “Materials and Methods.” (B) Full-length gp120 trimer model. The model was constructed by superposing CD4-bound monomer model on the Env structure derived from cryo-EM analysis (PDB code: 3DNO; Liu et al., 2008). Side and top views are shown on the left and on the right, respectively. V1/V2 and V3 regions are highlighted by red and blue colors, respectively.
