Improved interaction potentials for charged residuals in proteins
Article Abstract:
Accurate free energies involving charged groups from molecular simulations are obtained from reoptimizing OPLS-AA parameters by using Monte Carlo free energy perturbation. The new parameters are used directly in molecular simulations without any modification of neutral residues and are important in simulations where charged residues have changed the environment.

Simulation of an ensemble of conformational transitions in a united-residue model of calmodulin
Article Abstract:
The complete dynamical simulation of the structural transition of calmoulin is examined. A simple residue-level computer model of calmoudulin's N-terminal lobe results in a statistically converged ensemble of dynamic conformational transitions.
