Flexibility of Monomeric and Dimeric HIV-1 Protease†
The flexibility and stability of both monomeric and dimeric HIV-1 PR were explored by 100 ns implicit solvent molecular dynamics simulation at 350 K with the aim to correlate the monomer stability with the dimerization mechanism. The principal component analysis (PCA) was applied to visualize the available regions in the conformational space of the two HIV-1 PR forms, to compare their structura...
متن کاملHIV-1 protease inhibitors.
Treatment of human immunodeficiency virus type 1 (HIV-1) infection with regimens that include protease inhibitors (PIs) has contributed to marked improvements in HIV-related disease progression and mortality. Five PIs are approved by the US Food and Drug Administration and have potent activity in vitro. PIs with 2 nucleoside analogue reverse transcriptase inhibitors have demonstrated prolonged ...
متن کاملHIV-1 protease mutations and protease inhibitor cross-resistance.
The effects of many protease inhibitor (PI)-selected mutations on the susceptibility to individual PIs are unknown. We analyzed in vitro susceptibility test results on 2,725 HIV-1 protease isolates. More than 2,400 isolates had been tested for susceptibility to fosamprenavir, indinavir, nelfinavir, and saquinavir; 2,130 isolates had been tested for susceptibility to lopinavir; 1,644 isolates ha...
متن کاملCell killing by HIV-1 protease.
The human immunodeficiency virus protease (HIV-1 PR) was expressed both in the yeast Saccharomyces cerevisiae and in mammalian cells. Inducible expression of HIV-1 PR arrested yeast growth, which was followed by cell lysis. The lytic phenotype included loss of plasma membrane integrity and cell wall breakage leading to the release of cell content to the medium. Given that neither poliovirus 2A ...
متن کاملFolded monomer of HIV-1 protease.
The mature human immunodeficiency virus type 1 protease rapidly folds into an enzymatically active stable dimer, exhibiting an intricate interplay between structure formation and dimerization. We now show by NMR and sedimentation equilibrium studies that a mutant protease containing the R87K substitution (PR(R87K)) within the highly conserved Gly(86)-Arg(87)-Asn(88) sequence forms a monomer wit...
