Energy transfer in nonlinear network models of proteins

  title={Energy transfer in nonlinear network models of proteins},
  author={Francesco Piazza and Yves‐Henri Sanejouand},
We investigate how nonlinearity and topological disorder affect the energy relaxation of local kicks in coarse-grained network models of proteins. We find that nonlinearity promotes long-range, coherent transfer of substantial energy to specific functional sites, while depressing transfer to generic locations. In some cases, transfer is mediated by the self-localization of discrete breathers at distant locations from the kick, acting as efficient energy-accumulating centers.

Discrete breathers in a realistic coarse-grained model of proteins.
The combination of these two nonlinear effects may provide a ready means for remotely controlling local conformational changes in proteins and develop as energy-accumulating centres following perturbations even at distant locations.
Nonlinear network model analysis of vibrational energy transfer and localisation in the Fenna-Matthews-Olson complex
The nonlinear network model (NNM) is applied to the entire trimeric FMO complex and evidence for the existence of nonlinear discrete breather modes is found, potentially opening up alternative excitation energy transfer routes through their influence on pigment properties.
Nonlinear excitations match correlated motions unveiled by NMR in proteins: a new perspective on allosteric cross-talk.
The calculations provide a novel quantitative tool to predict fold-spanning dynamical pathways of correlated residues that may be central to allosteric cross-talk in proteins, and speculate that transient energy redistribution among the vibrational modes in a protein might favor the emergence of DB-like bursts of long-lived energy at hot-spot sites with lifetimes in the ns range.
Understanding on the residue contact network using the log-normal cluster model and the multilevel wheel diagram.
It is shown that the cluster sizes in a native protein follow the log-normal distribution for a dataset consisting of 424 proteins, the first time of such fitting for the native structures.
Out-of-Equilibrium Collective Oscillation as Phonon Condensation in a Model Protein
We describe the activation of out-of-equilibrium collective oscillations of a macromolecule as a classical phonon condensation phenomenon. If a macromolecule is modeled as an open system-that is, it
A donor-acceptor pair for the real time study of vibrational energy transfer in proteins.
This work addresses the requirements for extending this powerful approach to proteins and presents a protein-compatible donor-acceptor pair for the real time investigation of VET, and investigates the performance of the proposed VET pair in a model peptide designed to contain additional characteristic vibrational modes frequently used in infrared spectroscopy of proteins.
Allo-network drugs: extension of the allosteric drug concept to protein- protein interaction and signaling networks.
It is shown that most intra-protein conformational changes may be dynamically transmitted across protein-protein interaction and signaling networks of the cell, and that allo-network drugs influence the pharmacological target protein indirectly using specific inter-protein network pathways.
Wavelet imaging of transient energy localization in nonlinear systems at thermal equilibrium: The case study of NaI crystals at high temperature
In this paper we introduce a method to resolve transient excitations in time-frequency space from molecular dynamics simulations. Our technique is based on continuous wavelet transform of velocity
Cutoff lensing: predicting catalytic sites in enzymes
This paper introduces a simple, light and computationally inexpensive structure-based method to identify catalytic sites in enzymes and finds that the larger the structures the greater the predictive power afforded by the method.

The core‐periphery learning theory may increase the understanding of signaling, memory formation, information encoding and decision‐making processes and indicates that deliberative democracy is a slow yet efficient learning strategy developed as the success of a billion‐year evolution.


The value of the charge transfer when hydrogen bonds stretch is recalculated using quantum chemical methods which takes into account the whole nucleoside pairs, exploring the consequences on the properties of MBs, including the range of frequencies for which they exist and their effective masses.
Characterizing the unfolded states of proteins using single-molecule FRET spectroscopy and molecular simulations
Analysis of the donor fluorescence decay of the unfolded subpopulation of both proteins gives information about the end-to-end chain distribution and suggests that chain dynamics is slow compared with the donor life-time, whereas the bin-size independence of the small excess width above the shot noise for the FRET efficiency distributions may result from incomplete conformational averaging on even the 1-ms time scale.
Long-Lived Amide I Vibrational Modes in Myoglobin
Pump-probe experiments in the infrared measure vibrational relaxation rates, suggesting that the alpha helix in proteins can support nonlinear states of 15 ps characteristic times.
