Molecular dynamics simulations of nucleic acid-protein complexes

Molecular dynamics simulation studies of protein-nucleic acid complexes are more complicated than studies of either component alone-the force field has to be properly balanced, the systems tend to become very large, and a careful treatment of solvent and of electrostatic interactions is necessary. Recent investigations into several protein-DNA and protein-RNA systems have shown the feasibility of the simulation approach, yielding results of biological interest not readily accessible to experimental methods.
