Mechanistic studies on the DNA linking activity of Epstein-Barr nuclear antigen 1.

abstract：:Elastic network models (ENMs) are valuable and efficient tools for characterizing the collective internal dynamics of proteins based on the knowledge of their native structures. The increasing evidence that the biological functionality of RNAs is often linked to their innate internal motions poses the question of whet...
