There has been recent interest in the dynamics of both folding and folded proteins and the relation of protein dynamics to biological function. Among the dynamical aspects of biomolecules anomalous conformational diffusion, in particular subdiffusion, has attracted a lot of attention both in experimental [1] and theoretical [2] works. Subdiffusion can be seen in relativly small molecules such as peptides. Molecular dynamics simulation of peptides extending to several microseconds can provide the basis for a better understanding of conformational subdiffusion and the underlying mechanisms.
