文摘

•: Changes in the structure and dynamics of hydration waters due to glass transitions were investigated for bovine serum albumin by solid state ²H NMR.
•: The isotropic rotation of water molecules near the protein was restricted by freezing of the disordered region in the protein around T_g=200 K.
•: A 180° flip becomes the dominant motion for water molecules near protein below T_g = 200 K.
