On the Kinetic Behavior and Folding Properties of an Off-Lattice Heteropolymer Model
O. Sommelius
The kinetic behavior of a three-dimensional off-lattice heteropolymer model is studied in terms of the time dependence of the average mean-square displacement between configuration…
The Electrostatic Persistence Length Calculated from Monte Carlo, Variational and Perturbation Methods
M. Ullner, B. Jönsson, C. Peterson +2
Monte Carlo simulations and variational calculations using a Gaussian ansatz are applied to a model consisting of a flexible linear polyelectrolyte chain as well as to an intrinsic…
Local Interactions and Protein Folding: A 3D Off-Lattice Approach
Anders Irbäck, Carsten Peterson, Frank Potthast +1
The thermodynamic behavior of a three-dimensional off-lattice model for protein folding is probed. The model has only two types of residues, hydrophobic and hydrophilic. In absence…
Scaling and Scale Breaking in Polyelectrolyte
Carsten Peterson, Ola Sommelius, Bo Söderberg
We consider the thermodynamics of a uniformly charged polyelectrolyte with harmonic bonds. For such a system there is at high temperatures an approximate scaling of global properti…
Titrating Polyelectrolytes - Variational Calculations and Monte Carlo Simulations
B. Jönsson, M. Ullner, C. Peterson +2
Variational methods are used to calculate structural and thermodynamical properties of a titrating polyelectrolyte in a discrete representation. The Coulomb interactions are emulat…
