Filament flexibility enhances power transduction of F-actin bundles
Alessia Perilli, Carlo Pierleoni, Jean-Paul Ryckaert
The dynamic behavior of bundles of actin filaments growing against a loaded obstacle is investigated through a generalized version of the standard multi filaments Brownian Ratchet…
On the force--velocity relationship of a bundle of rigid living filaments
Alessia Perilli, Carlo Pierleoni, Giovanni Ciccotti +1
In various cellular processes, biofilaments like F-actin and F-tubulin are able to exploit chemical energy associated to polymerization to perform mechanical work against an extern…
On the Properties of a Bundle of Flexible Actin Filaments in an Optical Trap
Alessia Perilli, Carlo Pierleoni, Giovanni Ciccotti +1
We establish the Statistical Mechanics framework for a bundle of Nf living and uncrosslinked actin filaments in a supercritical solution of free monomers pressing against a mobile…
A semi-flexible model prediction for the polymerization force exerted by a living F-actin filament on a fixed wall
Carlo Pierleoni, Giovanni Ciccotti, Jean-Paul Ryckaert
We consider a single living semi-flexible filament with persistence length l_p in chemical equilibrium with a solution of free monomers at fixed monomer chemical potential mu_1 and…
On the pressure exerted by a bundle of independent living filaments
Jean-Paul Ryckaert, Sanoop Ramachandran
The properties of a bundle of grafted semi-flexible living filaments in ideal solution facing an obstacle wall, under supercritical conditions, are explored. For this purpose, we m…
Compressive force generation by a bundle of living biofilaments
Sanoop Ramachandran, Jean-Paul Ryckaert
To study the compressional forces exerted by a bundle of living stiff filaments pressing on a surface, akin to the case of an actin bundle in filopodia structures, we have performe…
Simulations of living filaments
Mathieu Caby, Priscilla Hardas, Sanoop Ramachandran +1
We propose a hybrid Molecular Dynamics/Multi-particle Collision Dynamics model to simulate a set of self-assembled semiflexible filaments and free monomers. Further, we introduce a…
Reaction kinetics of coarse-grained equilibrium polymers: a Brownian Dynamics study
C-C Huang, H. Xu, F. Crevel +2
Self-assembled linear structures like giant cylindrical micelles or discotic molecules in solution stacked in flexible columns are systems reminiscent of polydisperse polymer solut…
Single chain elasticity and thermoelasticity of polyethylene
John T. Titantah, Carlo Pierleoni, Jean-Paul Ryckaert
Single-chain elasticity of polyethylene at point up to 90% of stretching with respect to its contour length is computed by Monte-Carlo simulation of an atomistic model in conti…
Excluded volume effects on the structure of a linear polymer under shear flow
Carlo Pierleoni, Jean-Paul Ryckaert
The effect of excluded volume interactions on the structure of a polymer in shear flow is investigated by Brownian Dynamics simulations for chains with size . The…
On the signature of tensile blobs in the scattering function of a stretched polymer
Carlo Pierleoni, Gianluigi Arialdi, Jean-Paul Ryckaert
We present Monte Carlo data for a linear chain with excluded volume subjected to a uniform stretching. Simulation of long chains (up to 6000 beads) at high stretching allows us to…
