Structural determinants of HIV-1 reverse transcriptase stereoselectivity towards (beta)-L-deoxy- and dideoxy-pyrimidine nucleoside triphosphates: molecular basis for the combination of L-dideoxynucleoside analogs with non-nucleoside inhibitors in anti HIV chemotherapy.
We have compared the HIV-1 RT mutants containing the single substitutions L100I, K103N, V106A, V179D, Y181I and Y188L, known to confer NNI-resistance in treated patients, to HIV-1 RT wt for their sensitivity towards inhibition by D- and L-deoxy- and dideoxy-nucleoside tiphosphates. The results showed a differential effect of the substitutions on the affinity for both D- and L-enantiomers of deoxy- and dideoxy-nucleoside triphosphates and provide a rationale for the utilization of L-dideoxynucleoside analogs with NNI in combination chemotherapy.
