Polymer physics of intracellular phase transitions

CP Brangwynne, P Tompa, RV Pappu - Nature Physics, 2015 - nature.com
Intracellular organelles are either membrane-bound vesicles or membrane-less
compartments that are made up of proteins and RNA. These organelles play key biological …

Irreversibility and biased ensembles in active matter: Insights from stochastic thermodynamics

É Fodor, RL Jack, ME Cates - Annual Review of Condensed …, 2022 - annualreviews.org
Active systems evade the rules of equilibrium thermodynamics by constantly dissipating
energy at the level of their microscopic components. This energy flux stems from the …

Protein ensembles: how does nature harness thermodynamic fluctuations for life? The diverse functional roles of conformational ensembles in the cell

G Wei, W **, R Nussinov, B Ma - Chemical reviews, 2016 - ACS Publications
All soluble proteins populate conformational ensembles that together constitute the native
state. Their fluctuations in water are intrinsic thermodynamic phenomena, and the …

Ergodicity and large deviations in physical systems with stochastic dynamics

RL Jack - The European Physical Journal B, 2020 - Springer
In ergodic physical systems, time-averaged quantities converge (for large times) to their
ensemble-averaged values. Large deviation theory describes rare events where these time …

Markov state models provide insights into dynamic modulation of protein function

D Shukla, CX Hernández, JK Weber… - Accounts of chemical …, 2015 - ACS Publications
Conspectus Protein function is inextricably linked to protein dynamics. As we move from a
static structural picture to a dynamic ensemble view of protein structure and function, novel …

Accelerated molecular dynamics simulation for helical proteins folding in explicit water

L Duan, X Guo, Y Cong, G Feng, Y Li… - Frontiers in …, 2019 - frontiersin.org
In this study, we examined the folding processes of eight helical proteins (2I9M, TC5B,
1WN8, 1V4Z, 1HO2, 1HLL, 2KFE, and 1YYB) at room temperature using the explicit solvent …

Effective interactions and large deviations in stochastic processes

RL Jack, P Sollich - The European Physical Journal Special Topics, 2015 - Springer
We discuss the relationships between large deviations in stochastic systems, and “effective
interactions” that induce particular rare events. We focus on the nature of these effective …

Surface tensiometry of phase separated protein and polymer droplets by the sessile drop method

M Ijavi, RW Style, L Emmanouilidis, A Kumar, SM Meier… - Soft Matter, 2021 - pubs.rsc.org
Phase separated macromolecules play essential roles in many biological and synthetic
systems. Physical characterization of these systems can be challenging because of limited …

Amyloid assembly is dominated by misregistered kinetic traps on an unbiased energy landscape

Z Jia, JD Schmit, J Chen - Proceedings of the National Academy of …, 2020 - pnas.org
Atomistic description of protein fibril formation has been elusive due to the complexity and
long time scales of the conformational search. Here, we develop a multiscale approach …

[HTML][HTML] Variational control forces for enhanced sampling of nonequilibrium molecular dynamics simulations

A Das, DT Limmer - The Journal of chemical physics, 2019 - pubs.aip.org
We introduce a variational algorithm to estimate the likelihood of a rare event within a
nonequilibrium molecular dynamics simulation through the evaluation of an optimal control …
