TABLE 1.
Summary of the single nucleotide incorporation kinetic constants for HIV-RT at position n Km is in μm dGTP or ETV-TP. kcat is in min–1. Selectivity is defined as a ratio of kcat/Km for dGTP over kcat/Km for ETV-TP. S.D. was determined on the basis of at least three independent experiments.
