Exploring Downhill Protein Folding Free Energy Landscapes
Downhill protein folding, i.e., folding with the free energy barrier comparable to the thermal energy kBT, is investigated by combining laser induced temperature-jump kinetics measurements and Langevin dynamics simulations. A kinetic and thermodynamic survey of multiple WW domain mutants is …

Barrier Heights and Diffusion Coefficients in Protein Folding
A widely held view with respect to the folding of single-domain proteins is that they are two-state. In other words, it is seemingly sufficient to invoke just two thermodynamic macrostates - folded and unfolded - to explain the experimental data with a transition-state like picture. Unfortunately, …

Fast Protein and RNA Folding on a Rough Energy Landscape
… approach with other experimental methods, the folding process of protein assembly, protein molecules, and RNA molecules was focused in this work. For the first time, time-resolved self-assembly of a light-harvesting protein complex was studied using the laser T-jump method. Experiment results …

Temperature- and pressure-induced protein dynamics from microseconds to minutes
For the past two decades, protein folding experiments have been speeding up from the second or millisecond time scale to the microsecond time scale, and full-atom simulations have been extended from the nanosecond to the microsecond and even millisecond time scale. Where the two meet, it is now …

THERMODYNAMIC PROPERTIES OF THE UNFOLDED ENSEMBLE OF PROTEINS
… on the unfolded ensemble of BBL, a globally downhill folding 40-residue protein involved the Krebs cycle of <italic>E. coli</italic>, in its acid-denatured state, and on a sequence-randomized version of this protein. The effect of variability in thermodynamic conditions, such as temperature …

Protein folding in living cells and under pressure
Protein folding, the process through which proteins gain their functional structure, can be approached from the perspective of many disciplines. Starting with biology, we can probe how protein structure relates to function and consider how the fold of a protein interacts with the biological …

In vitro and in vivo protein folding under stress
… stress on proteins including some of the fast-folding model proteins, who’s in vitro folding can be fully simulated on computers and compared directly with experiments. Pressure and temperature are prototypical perturbations that illustrate how close many proteins are to instability, a property …
