Figure 2From: The M50I polymorphic substitution in association with the R263K mutation in HIV-1 subtype B integrase increases drug resistance but does not restore viral replicative fitnessAddition of M50I to R263K does not increase integrase strand-transfer activity. Strand-transfer activity and Vmax/1/2MaxProt of wild-type and mutant enzymes. A) Relative strand-transfer activity when varying protein concentration. B) Vmax values. C)1/2MaxProt values. D) Enzyme efficiency as determined by the division of Vmax by 1/2MaxProt. Error bars represent the standard errors of the means (SEM).Back to article page
