K65R and K65A substitutions in HIV-1 reverse transcriptase enhance polymerase fidelity by decreasing both dNTP misinsertion and mispaired primer extension efficiencies

The Lys65 residue, in the fingers domain of HIV reverse transcriptase (RT), interacts in a sequence independent fashion with the incoming dNTP. Previously, we showed that a 5 amino acid deletion spanning Lys65 and a K65A substitution both enhanced the fidelity of dNTP insertion. We hypothesized that...
