HIV-1 protease-substrate coevolution in nelfinavir resistance.
UNLABELLED Resistance to various human immunodeficiency virus type 1 (HIV-1) protease inhibitors (PIs) challenges the effectiveness of therapies in treating HIV-1-infected individuals and AIDS patients. The virus accumulates mutations within the protease (PR) that render the PIs less potent. Occasionally, Gag sequences also coevolve with mutations at PR cleavage sites contributing to drug resis...
متن کاملLocal and spatial factors determining HIV-1 protease substrate recognition.
Insertional mutagenesis of the Escherichia coli thymidylate synthase (TS) was used to address substrate recognition of HIV-1 protease in a well characterized structural context. By modifying the TS conformation while maintaining its enzymic activity, we investigated the influence of protein folding on protease-substrate recognition. A slight destabilization of the TS structure permitted the cle...
متن کاملStructural basis and distal effects of Gag substrate coevolution in drug resistance to HIV-1 protease.
Drug resistance mutations in response to HIV-1 protease inhibitors are selected not only in the drug target but elsewhere in the viral genome, especially at the protease cleavage sites in the precursor protein Gag. To understand the molecular basis of this protease-substrate coevolution, we solved the crystal structures of drug resistant I50V/A71V HIV-1 protease with p1-p6 substrates bearing co...
متن کاملSubstrate envelope-designed potent HIV-1 protease inhibitors to avoid drug resistance.
The rapid evolution of HIV under selective drug pressure has led to multidrug resistant (MDR) strains that evade standard therapies. We designed highly potent HIV-1 protease inhibitors (PIs) using the substrate envelope model, which confines inhibitors within the consensus volume of natural substrates, providing inhibitors less susceptible to resistance because a mutation affecting such inhibit...
متن کاملDesign of mutation-resistant HIV protease inhibitors with the substrate envelope hypothesis.
There is a clinical need for HIV protease inhibitors that can evade resistance mutations. One possible approach to designing such inhibitors relies upon the crystallographic observation that the substrates of HIV protease occupy a rather constant region within the binding site. In particular, it has been hypothesized that inhibitors which lie within this region will tend to resist clinically re...
