Increased misincorporation fidelity observed for nucleoside analog resistance mutations M184V and E89G in human immunodeficiency virus type 1 reverse transcriptase does not correlate with the overall error rate measured in vitro.

Abstract excerpt

Nucleoside analog-resistant variants of human immunodeficiency virus type 1 (HIV-1) reverse transcriptase (RT) that displayed higher in vitro polymerase fidelity were previously identified via nucleotide insertion and mispair extension assays. To evaluate the contribution of increased nucleotide insertion and primer extension fidelities on the overall error rate of HIV-1 RT, we have measured the impact of two...
