Web26 sep. 1995 · The major part of the lysozyme molecules (86%) refold on a slow kinetic pathway with well-populated partially folded states. Additionally, 14% of the molecules fold faster. The rate constant of formation of native molecules on the fast pathway corresponds well to the rate constant expected for folding to occur by a two-state process without any ... Although most proteins are known to follow Anfinsen’s thermodynamic hypothesis, there are a few that fold under kinetic control (Baker and Agard, 1994; Eder and Fersht, 1995). An interesting example is ɑ-lytic protease (Fig. 3A), which has a folding intermediate that is kinetically trapped as a result of high … Meer weergeven Understanding how proteins achieve their three-dimensional structure (i.e. how they fold) is one of the most compelling problems in … Meer weergeven Recent studies (Addabbo et al., submitted) found that, immediately after translation termination, newly synthesized proteins kinetically partition between the fully folded native state … Meer weergeven Large-scale aggregation of proteins—whose biological function requires monomers or monodisperse lower-order … Meer weergeven Kinetic trapping under physiological conditions is not a unique characteristic of protein folding and aggregation.

Web26 okt. 1999 · Analysis of these data reveals the presence of a Mg 2+ -stabilized kinetic trap that slows folding at higher Mg 2+ concentrations. Thus, the Tetrahymena ribozyme folds with an optimal rate at 2 mM Mg 2+, just above the concentration required for stable structure formation. These results suggest that thermodynamic and kinetic folding of … the help true story or not
