A) Schematic representation of the ATP-mediated excision assay used in this study. Experimental details are provided in the Materials and Methods. AZT-MP is designated as āZā
B) Representative autoradiogram of AZT-MP excision reactions carried out by WT and mutant RT on RNA/DNA and DNA/DNA T/Ps. The reaction times were 3, 5, 10, 15, 30, 60 and 90 min.
C) Isotherms of ATP-mediated AZT-MP excision reactions carried out by WT and mutant HIV-1 RT on a DNA/DNA T/P (left-hand curve) and on an RNA/DNA T/P (right-hand curve). Data are the mean Ā± standard deviation from at least three independent experiments.
