Molecular dynamics simulations of DNA–DNA and DNA–protein interactions

摘要

The all-atom molecular dynamics method can characterize the molecular-level interactions in DNA and DNA–protein systems with unprecedented resolution. Recent advances in computational technologies have allowed the method to reveal the unbiased behavior of such systems at the microseconds time scale, whereas enhanced sampling approaches have matured enough to characterize the interaction free energy with quantitative precision. Here, we describe recent progress toward increasing the realism of such simulations by refining the accuracy of the molecular dynamics force field, and we highlight recent application of the method to systems of outstanding biological interest.
