Abstract

Measurement of the low temperature neutron excess of scattering of H2O-hydrated plastocyanin relative to D2O-hydrated protein allowed us to reveal the presence of an inelastic peak at about 3.5 meV. This excess of vibrational modes, elsewhere termed "boson peak," is due to the dynamical behavior ofthe water molecules belonging to the H2O-hydration shell surrounding the protein. The relevance of the boson peak to the dynamical coupling between the solvent and the protein, and hence to the protein functionality is addressed. [S1063-651X(99)50809-X].
