FIG. 1.
Amino acid sequences of virus clones LW_H8res and LW_G9sens in comparison to IIIB. The viruses were isolated by limiting dilution from PBMCs infected with an isolate (FF3346) obtained 7 years after accidental infection of a laboratory worker. The predicted amino acid sequences of the envelope glycoproteins were derived from the consensus sequences of the envelope fragments ranging from V1 to V5, which were amplified and sequenced from DNA isolated from infected PBMC cultures. Variable and constant domains are indicated, and the numbering of amino acid positions is relative to HXB2; dots indicate residues identical to those in the reference sequence, and dashes indicate amino acid deletions relative to HXB2. The location of the restriction site for StuI is also depicted.
