Glassy, nonexponential relaxations in globular proteins are typically attributed to conformational behaviors that are missing from intrinsically disordered proteins. Yet, we show that single molecules of a disordered-protein construct display two signatures of glassy dynamics, logarithmic relaxations and a Kovacs memory effect, in response to changes in applied tension. We attribute this to the presence of multiple independent local structures in the chain, which we corroborate with a model…

Ubiquitous Dynamical Time Asymmetry in Measurements on Materials and Biological Systems

Many measurements on soft condensed matter (e.g., biological and materials) systems track lowdimensional observables projected from the full system phase space as a function of time. Examples are

Order from Disorder with Intrinsically Disordered Peptide Amphiphiles

New peptide amphiphiles composed of an intrinsically disordered peptide conjugated to two variants of hydrophobic dendritic domains exhibit a sharp pH-induced micellar phase-transition from low-dispersity spheres to extremely elongated worm-like micelles.

Strong non-exponential relaxation and memory effects in a fluid with non-linear drag

We analyse the dynamical evolution of a fluid with non-linear drag, for which binary collisions are elastic, described at the kinetic level by the Enskog-Fokker-Planck equation. This model system,

Anomalous heating in a colloidal system

Significance A cold system normally takes longer to warm up than a cool system. Yet recent theoretical studies have suggested that the reverse may sometimes be possible. Here, using a colloidal

Universal non-exponential relaxation and memory effects in a fluid with non-linear drag

We analyse the dynamical evolution of a fluid with non-linear drag, for which binary collisions are elastic, at the kinetic level of description. When quenched to low temperatures, the system



Neurofilaments Function as Shock Absorbers: Compression Response Arising from Disordered Proteins.

Using x-ray scattering, this work measures the compression response of disordered protein hydrogels, which are the main stress-responsive component of neuron cells and finds that at high compression their mechanics are dominated by gaslike steric and ionic repulsions.

Single-molecule force spectroscopy reveals signatures of glassy dynamics in the energy landscape of ubiquitin

The conformational energy landscape of a protein out of equilibrium is poorly understood. We use single-molecule force-clamp spectroscopy to measure the kinetics of unfolding of the protein ubiquitin

Results of this analysis showed that intrinsically unstructured proteins do not possess uniform structural properties, as expected for members of a single thermodynamic entity, and the Protein Quartet model, with function arising from four specific conformations (ordered forms, molten globule, premolten globules, and random coils) is discussed.

The energy landscapes and motions of proteins.

The concepts that emerge from studies of the conformational substates and the motions between them permit a quantitative discussion of one simple reaction, the binding of small ligands such as carbon monoxide to myoglobin.

Charge interactions can dominate the dimensions of intrinsically disordered proteins

This work uses single-molecule Förster resonance energy transfer to investigate the influence of charged residues on the dimensions of unfolded and intrinsically disordered proteins and finds that IDPs can exhibit a prominent expansion at low ionic strength that correlates with their net charge.

Observation of strange kinetics in protein folding.

Highly nonexponential folding kinetics in aqueous solution have been observed during temperature jump-induced refolding of two proteins, yeast phosphoglycerate kinase and a ubiquitin mutant, and are reconciled with exponential kinetics measured under different experimental conditions and with titration experiments indicating cooperative folding.

The Kovacs effect in model glasses

We discuss the 'memory effect' discovered in the 1960s by Kovacs in temperature shift experiments on glassy polymers, where the volume (or energy) displays a non-monotonic time behaviour. This effect
