The conserva- tive nature of the env gene variability was further high- lighted by the finding that, in many of the positions, the variant amino acid in the SRV-2 isolate was an amino acid found ... 87% of the amino acids within the 574 amino acid env sequence exhibited no variation in the different SRV-2 isolates examined (Figures 2 and 3). Within t...
