Amino acid sequences of protease-encoding regions of HIV-1NL4-3 variants selected in the presence of GRL-216, GRL-246, GRL-286, or GRL-396. The amino acid sequence of protease, deduced from the nucleotide sequence of the protease-encoding region of each proviral DNA isolated at each time indicated, is shown. The amino acid sequence of wild-type HIV-1NL4-3 protease is illustrated at the top as a reference.
