Crystal structure of [L-Ala51/51']HIV-1 protease with reduced isostere MVT-101 inhibitorCrystal structure of [L-Ala51/51']HIV-1 protease with reduced isostere MVT-101 inhibitor
Structural highlights
Publication Abstract from PubMedWe have used chemical protein synthesis and advanced physical methods to probe dynamics-function correlations for the HIV-1 protease, an enzyme that has received considerable attention as a target for the treatment of AIDS. Chemical synthesis was used to prepare a series of unique analogues of the HIV-1 protease in which the flexibility of the "flap" structures (residues 37-61 in each monomer of the homodimeric protein molecule) was systematically varied. These analogue enzymes were further studied by X-ray crystallography, NMR relaxation, and pulse-EPR methods, in conjunction with molecular dynamics simulations. We show that conformational isomerization in the flaps is correlated with structural reorganization of residues in the active site, and that it is preorganization of the active site that is a rate-limiting factor in catalysis. Protein conformational dynamics in the mechanism of HIV-1 protease catalysis.,Torbeev VY, Raghuraman H, Hamelberg D, Tonelli M, Westler WM, Perozo E, Kent SB Proc Natl Acad Sci U S A. 2011 Dec 27;108(52):20982-7.
