Abstract: To assess the impact of drug resistance mutations on the activity of
IN of HIV-1 subtype A strain FSU-A, which is dominant in Russia, variants of the consensus
IN of this subtype containing the primary resistance mutations
G118R and
Q148K and secondary compensatory substitutions
E138K and
G140S were prepared and characterized.
Result: A similar observation was made earlier for HIV-1 subtype B: the addition of the
E138K mutation to the
Q148K/
G140S substitutions improved viral replication whi
