Abstract

Molecular dynamics simulations of dry and partially hydrated plastocyanin have been performed at 13 temperatures, in the 20-350 K range, for 600 ps to investigate the role of hydration water on the thermal activation of protein dynamics. The analysis of results points out that asharp dynamical transition occurs in the hydrated protein at about 220 K; such a transition appearing to be smeared out in the dry protein. The dynamical transition, which is much more marked for the solvent-exposed side chains than for the C-alpha atoms, is strongly coupled to the hydrogen bond network restructuring dynamics involving the interfacial water.
