Figure 6

Schematic representation of HIV-1 gp120 structural domains. (A) Linear representation of the gp120 amino acid sequence. (Colored rectangles) Variable domains; (colored lines) disulfide bonds between conserved cysteine residues. (B) Folded representation of the HIV-1 gp120. Disulfide bonds are shown in color, and N-linked oligosaccharide side chains are shown as branched structures. Gray regions depict domains involved in CD4 binding. (Modified from Leonard et al. [1990] and Pollard et al. [1992].)
