Primer extension assay in the presence or absence of ATP.

a.The sequence of HIV RT WT and mutant derived from BH10.b.Data are means ± standard deviations from at least three independent experiments.c.The relative increase in IC50 value compared with each HIV-1 RT WT without, or with ATP is given in parentheses. Bold indicates an increase in fold increase value greater than 3-fold.d.Excision enhancement due to ATP is calculated as IC50 with ATP/IC50 without ATP.
