Dependence of Internal Friction on Folding Mechanism
An outstanding challenge in protein folding is understanding the origin of "internal friction" in folding dynamics, experimentally identified from the dependence of folding rates on solvent viscosity. A possible origin suggested by simulation is the crossing of local torsion barriers. However, it was unclear why internal friction varied from protein to protein or for different folding barriers ...
متن کاملThe Mechanism of Internal Friction Peak Associated with the Subboundaries
I t has been indicated that subboundaries apperar to have difficulty in sliding. This payer propose three mechanisms of the internal friction peak associated with subboundaries: diffusion ~ r e e p , ~ l i d e and climb of the jogged dislocations in subboundaries and the interaction of subboundaries and dislocations. We have analysed and calculated the internal friction

متن کاملInternal friction in enzyme reactions.
The empirical concept of internal friction was introduced 20 years ago. This review summarizes the results of experimental and theoretical studies that help to uncover the nature of internal friction. After the history of the concept, we describe the experimental challenges in measuring and interpreting internal friction based on the viscosity dependence of enzyme reactions. We also present spe...
متن کاملInternal Friction in Concentrated Alloys
Internal friction in concentrated alloys at kHz frequencies and at temperatures from 120 3 0 0 K has been studied in alpha-and beta-brasses as a function of grain size, temperature and pre-strain, and a statistical model has been proposed to account for the observations.
