| Research Abstract |
The correlation between the antifreeze effect of AFP and the structure and dynamics of hydration water of the protein was studied by X-ray and neutron scatterings (quasi-elastic neutron scattering, inelastic X-ray scattering, and X-ray diffraction) and MD simulation. Although the dynamic transition of the hydrated protein was observed, water structure of hydration water changed insignificantly. Compared with the result of hydration water of the other proteins and confined water in mesoporous materials, the transition between high density water and low density water was discussed.
