FIG. 6.

Comparison of the abilities of the various HIV-1 RTs (mutant and wild-type [WT]) to excise ddTMP and extend the primer in the presence of ddTTP and various concentrations of ATP. The assay conditions are similar to those described in the legend to Fig. 5, except that instead of AZTMP, the primer was terminated with ddTMP and, in the reaction mixtures, ddTTP was substituted for AZTTP. (A) Reactions run in the presence of 10 μM concentrations of each of the dNTPs. (B) Reactions run in the presence of 100 μM concentrations of each of the dNTPs.
