Figure 2. Inhibition of RT Polymerization by AZTTP.
The assay was done as previously described [1]. Normal dNTPs were present in the reaction at 10.0 μM each. Increasing concentrations of AZTTP were added, and the level of radioactive [α−32P]dCTP incorporated into the template/primer was measured. The level of radioactivity incorporated in the absence of analog was considered 100% activity; the other reactions were normalized to this value. The error bars are included; however, they are partially obscured by the data symbols. RT1 and RT2 designate the HIV RT backbone in which the Q151M mutation was made: HIV-1 or HIV-2.
