Communication: folding of glycosylated proteins under confinement.
Conjugating flexible polymers (such as oligosaccharides) to proteins or confining a protein in a restricted volume often increases protein thermal stability. In this communication, we investigate the interplay between conjugation and confinement which is not trivial as the magnitude and the mechanism of stabilization are different in each instance. Using coarse-grained computational approach th...
متن کاملEffects of confinement and crowding on folding of model proteins
We perform molecular dynamics simulations for a simple coarse-grained model of crambin placed inside of a softly repulsive sphere of radius R. The confinement makes folding at the optimal temperature slower and affects the folding scenarios, but both effects are not dramatic. The influence of crowding on folding are studied by placing several identical proteins within the sphere, denaturing the...
متن کاملThermodynamics and kinetics of protein folding under confinement.
Understanding the effects of confinement on protein stability and folding kinetics is important for describing protein folding in the cellular environment. We have investigated the effects of confinement on two structurally distinct proteins as a function of the dimension d(c) and characteristic size R of the confining boundary. We find that the stabilization of the folded state relative to bul...
متن کاملOsmolyte-Induced Folding and Stability of Proteins: Concepts and Characterization
It is well-known that the typical protein’s three-dimensional structure is relatively unstable in harsh conditions. A practical approach to maintain the folded state and thus improve the stability and activity of proteins in unusual circumstances is to directly apply stabilizing substances such as osmolytes to the protein-containing solutions. Osmolytes as natural occurring organic molecules ty...
