VRX-329747-selected mutations in HIV-1 RT. HIV-1 RT amino acids 1 to 550 are represented on the top line of the figure. Individual proviral clones recovered by PCR and characterized by sequence analysis are listed horizontally for 0.8, 1.6, 3.2, 6.4, and 20 μM VRX-329747. The dominant mutations M41L, A62T/V, S68N, G112S, V118I, and M184V are shaded.
