Autoprocessing: an essential step for the activation of HIV-1 protease.
Human immunodeficiency virus type 1 (HIV-1) expresses its structural and functional proteins within Gag-Pol precursor polyproteins. Specific proteolytic processing of the precursors by the viral protease is critical for the maturation and infectivity of viral particles. To observe the influence of autoprocessing on the activation of recombinant HIV-1 protease, we constructed different HIV-1 pro...
متن کاملDesign of a folding inhibitor of the HIV-1 Protease
Being HIV–1–PR an essential enzyme in the viral life cycle, its inhibition can control AIDS. Because the folding of single domain proteins, like HIV–1–PR is controlled by local elementary structures (LES, folding units stabilized by strongly interacting, highly conserved amino acids) which have evolved over myriads of generations to recognize and strongly attract each other so as to make the pr...
متن کاملA folding inhibitor of the HIV-1 protease.
Because the human immunodeficiency virus type 1 protease (HIV-1-PR) is an essential enzyme in the viral life cycle, its inhibition can control AIDS. The folding of single-domain proteins, like each of the monomers forming the HIV-1-PR homodimer, is controlled by local elementary structures (LES, folding units stabilized by strongly interacting, highly conserved, as a rule hydrophobic, amino aci...
متن کاملNMR elucidation of early folding hierarchy in HIV-1 protease.
Folding studies on proteases by the conventional hydrogen exchange experiments are severely hampered because of interference from the autolytic reaction in the interpretation of the exchange data. We report here NMR identification of the hierarchy of early conformational transitions (folding propensities) in HIV-1 protease by systematic monitoring of the changes in the state of the protein as i...
متن کاملalpha-lytic protease precursor: characterization of a structured folding intermediate.
The bacterial alpha-lytic protease (alphaLP) is synthesized as a precursor containing a large N-terminal pro region (Pro) transiently required for correct folding of the protease [Silen, J. L., and Agard, D. A. (1989) Nature 341, 462-464]. Upon folding, the precursor is autocatalyticly cleaved to yield a tight-binding inhibitory complex of the pro region and the fully folded protease (Pro/alpha...
