  author={Prasanta Kundu and Arti Dua},
  journal={arXiv: Statistical Mechanics},
The mean time of contact formation between two ends of a protein chain shows power law dependence with respect to the number of residues, $\tau_{CF} \sim N^{\alpha}$. Fluorescence quenching measurements based on triplet-triplet energy transfer show variation in the value of scaling exponent $\alpha$ for different protein-solvent systems. Here, starting from a non-Markovian diffusion equation supplemented with an exponential sink term that accounts for the energy transfer reaction between donor…

Effects of solvent quality on contact formation dynamics of polymer chain
Abstract We investigate the interplay effects of internal friction and solvent quality on the contact formation dynamics based on non-Markovian diffusion equation supplemented with an exponential
Mechanical Unfolding of Single Polyubiquitin Molecules Reveals Evidence of Dynamic Disorder
An approach for dynamic disorder is presented based on Zwanzig’s fluctuating bottleneck model, in which the rate of the reaction is controlled by the passage through the cross-sectional area of the bottleneck, which captures the very essence of dynamic disorder in single-molecule pulling experiments.
A Revisit to Turnover Kinetics of Individual Escherichia coli β-Galactosidase Molecules.
A dual approach to the single-enzyme reaction is suggested, independently, making important improvements over the parent study and the recently suggested two-state stochastic analyses followed by quantitative rationalization of the experimental data.


Effects of chain stiffness on the dynamics of loop formation in polypeptides. Appendix: Testing a 1-dimensional diffusion model for peptide dynamics
Quenching of the triplet state of tryptophan by cysteine provides an important new tool for measuring the rate at which a specific intramolecular contact is formed in disordered polypeptides. By
Dynamics of chain closure: approximate treatment of nonlocal interactions.
The Wilemski-Fixman model of diffusion controlled-reactions [J. Chem. Phys. 58, 4009 (1973)] is combined with a generalized random walk description of chain conformations to predict the dependence of
Measuring the rate of intramolecular contact formation in polypeptides.
A method is described for studying contact formation between tryptophan and cysteine based on measurements of the lifetime of the tryPTophan triplet state, showing that this rate is also close to the diffusion-limited rate of contact formation.
The dynamics of chain closure in semiflexible polymers
The mean first passage time of cyclization \tau of a semiflexible polymer with reactive ends is calculated using the diffusion-reaction formalism of Wilemski and Fixman [J. Chem. Phys. 60, 866
Peptide loop-closure kinetics from microsecond molecular dynamics simulations in explicit solvent.
Study of loop-closure kinetics for two peptides of different lengths in multiple all-atom explicit-solvent molecular dynamics simulations with different initial conditions and force fields to analyze the dynamics of peptides in the unfolded state with atomic resolution, thus probing early events in protein folding.
Exploring the role of internal friction in the dynamics of unfolded proteins using simple polymer models.
The Rouse model with internal friction (RIF), and its non-free draining analog, Zimm model withinternal friction, are used to explore the effect of internal friction on the rate with which intramolecular contacts can be formed within the unfolded chain.
Kinetics of loop formation in polymer chains.
The kinetics of contact formation between the ends of the chain are profoundly effected when interactions between monomers are taken into account, and the values of tau(c) decrease by more than 2 orders of magnitude when the solvent quality changes from good to poor.
Effects of the internal friction and the solvent quality on the dynamics of a polymer chain closure.
The single exponential distributions of the closure time in poor solvents suggest that the negative excluded volume of segments does not alter the nearly Poisson statistical characteristics of the process of the chain closure.
Dynamics of chain molecules. Intramolecular diffusion controlled reactions for a pair of terminal reactive groups
The first order intramolecular rate constant for the reaction between the terminal groups of flexible macromolecules is calculated in the partial draining case, following the theory formulated by
Dynamics of unfolded polypeptide chains as model for the earliest steps in protein folding.
The time constants for formation of the earliest intrachain contacts during protein folding are determined using triplet-triplet energy transfer and good solvents for polypeptide chains like EtOH, GdmCl and urea were found to slow intrachains diffusion and to decrease chain stiffness.
