Link In this study, the function of conserved gp120 contact residues, Leu593, Trp596, Gly597, Lys601, and Trp610 within the disulfide-bonded region of gp41, was examined in envelope glycoproteins derived from diverse HIV-1 isolates. They found that the gp120-gp41 association function of the disulfide-bonded region is conserved. However, the contribution of individual residues to gp41 folding and/or stability, gp120-gp41 association, membrane fusion function, and viral entry varied from isolate to isolate.
