FIG. 5.

Full-length envelope sequences of viral clones from patient T28 (A) and patient T5 (B) used in this study. The N-terminal 71 residues of the envelope glycoproteins (upstream of the MluI restriction site) as well as the C-terminal 106 residues (downstream of the BamHI restriction site) are derived from NL4-3. Amino acid identity (·), insertions/deletions (−), or substitutions are indicated. The first amino acid of each variable (V) and conserved (C) region is indicated in boldface. The potential N-linked glycosylation sites that differed in clones from the same patient are shown as shaded boxes.
