Collective protein dynamics in relation to function

Several techniques for the analysis of the internal motions of proteins are available — separating large collective motions from small, presumably uninteresting motions. Such descriptions are helpful in the characterization of internal motions and provide insight into the energy landscape of proteins. The real challenge, however, is to relate large collective motions to functional properties, such as binding and regulation, or to folding. These issues have been recently addressed in several papers.
