In Silico and In Vitro Comparison of HIV-1 Subtypes B and CRF02_AG Integrases Susceptibility to Integrase Strand Transfer Inhibitors

Table 2

Docking binding energies of RAL, ELV and L731,988 on the HIV-1 IN from B and CRF02_AG strains predicted by Autodock and Glide. The targets are the IN model with one Mg2+ cation in the active site (apo state, models 1 and 2) and IN·DNA model with two Mg2+ cations (holo state, models 3 and 4).
