Result: All tested RTs showed similar or increased catalytic efficiencies (measured as the ratio kcat/Km) in comparison with the O_WT RT, and the mutant enzyme V75I (O_V75I), as well as with the BH10_WT RT.
Result: Although position +149 could be considered as a common hot spot location for both mutant RTs, identified errors were one-nucleotide deletions in the case of O_V75I/D443N RT and base substitutions (mostly G T mutations) in the case of O_V75I/E478Q RT.
Result: For example, the spectrum of O_D443N PMID: 23840622

Method: The Q151M complex of mutations was defined as Q151M alone or in combination with one or more of the following mutations: A62V, V75I, F77L, and F116Y.
Chemical system biology based molecular interactions to identify inhibitors against Q151M mutant of HIV-1 reverse transcriptase.
Result: In our study, other NRTI-RAMs known to be associated with Q151M-mediated multi-nucleoside resistance including A62V, V75I, F77L, and F116Y, were also significantly more common in patients harboring the Q151M mutation (p<0.001).
Major groove binding track residues of the connection subdomain of human immunodeficiency virus type 1 reverse transcriptase enhance cDNA synthesis at high temperatures.
Discussion: In HIV, decreased binding of AZT is conferred initially in the presence of the primary Q151M mutation, followed by secondary mutations F77L, A62V, V75I and F116Y.
Low rates of nucleoside reverse transcriptase inhibitor resistance in a well-monitored cohort in South Africa on antiretroviral therapy.
Introduction: showed that the mutation Val75Ile increased the mismatch extension fidelity 3-fold while showing no apparent effect on misinsertion fidelity.
Differential in vitro kinetics of drug resistance mutation acquisition in HIV-1 RT of subtypes B and C.
Discussion: Q151M is a primary mutation that in vivo can be co-selected together with a group of secondary mutations (A62V, V75I, F77L and F116Y) that confers a cross-resistance with all NRTIs.
Monitoring HIV viral load in resource limited settings: still a matter of debate?
Result: The most frequent TAMs were T215F/Y (11/12, 91.7%), M41L (10/12, 83.3%), L210W (3/12, 27,3%), D67N (3/12, 25.0%), K70R (1/12, 8.3%) and V75I (1/12, 8.3%) (Table 3).

8Discussion: The A62V/V75I/F77L/F116Y/Q151M set of mutations is known as the ""Q151M"" complex RT, and has been known as a multidrug-resistance mutation, since the latter mutations are known to be involved in resistant variants with reduced susceptibility to dideoxynucleotides and to AZT."
Result: In addition, another mutant HIV-1 RT (A62V/V75I/F77L/F116Y/Q151M) was included in drug susceptibility assays.
Discussion: We report that both EFdA-TP and ENdA-TP are very potent inhibitors of N348I,
