Mechanistic role of residue Gln151 in error prone DNA synthesis by human immunodeficiency virus type 1 (HIV-1) reverse transcriptase (RT). Pre-steady state kinetic study of the Q151N HIV-1 RT mutant with increased fidelity.

Abstract excerpt

It has previously been reported that mutations in the Gln(151) residue of human immunodeficiency virus type 1 (HIV-1) reverse transcriptase (RT) greatly enhance RT fidelity. In this study, we employed pre-steady state kinetic assays to elucidate the mechanistic role of residue Gln(151) in highly error prone DNA synthesis by HIV-1 RT. Using our Q151N high fidelity mutant, which is structurally altered in its...
