Protein-nucleic acid recognition: simulation of base and "model" amino acids complexes in DMSO by the Monte Carlo method.

abstract：:We have performed an 4-ns MD simulation of calmodulin complexed with a target peptide in explicit water, under realistic conditions of constant temperature and pressure, in the presence of a physiological concentration of counterions and using Ewald summation to avoid truncation of long-range electrostatic forces. Dur...
