Under drug selection pressure, emerging mutations render HIV-1 protease drug resistance, leading to the therapy failure in anti-HIV treatment.Tthe multidrug-resistant 769 (MDR) HIV-1 protease (resistant mutations at residues 10, 36, 46, 54, 62, 63, 71, 82, 84, 90) is selected for the present study to understand drug resistance issue.
Ten additional mutations are introduced to MDR769 HIV-1 protease to study the structural influences brought by these mutations. We get crystal structures of four variants (I10V, A82F, A82S and A82T) of MDR769 HIV-1 protease. All these mutations fail to further open the flaps and expand the active site cavity of MDR769 …
