Binding mode prediction of Strand Transfer HIV-1 Integrase Inhibitors using Tn5 transposase as a plausible surrogate model for HIV-1 Integrase

The crystal structure of Tn5 transposase-DNA complex was used in docking experiments to predict binding modes of HIV-1 integrase strand transfer inhibitors (INSTIs). In fact, the identification of HIV-1 integrase inhibitors from an in vitro screen using Tn5 transposase as the target has been recently reported. Our results suggest the utility of this protein as a useful surrogate model for IN and also for in silico screening, in the search for new potential INSTIs.
