Collective Variable Description of Native Protein Dynamics
Steven Hayward,Nobuhiro Go +1 more
TL;DR: The normal-mode refinement method of protein X-ray crystallography, which is developed based on the concept of the above important subspace, is discussed and indicates that most important conformational events are taking place in a conformational subspace spanned by a rather small number of principal modes.
