==THE CRYSTAL STRUCTURES OF LYSOZYME AT VERY LOW LEVELS OF HYDRATION==
-
Earlier studies involving water-mediated transformations in lysozyme and, ribonuclease A have shown that the overall movements in the protein, molecule consequent to the reduction in the amount of surrounding water, are similar to those that occur during enzyme action, thus highlighting, the relationship among hydration, plasticity, and action of these enzymes., Monoclinic lysozyme retains its crystallinity even when the level of, hydration is reduced further below that necessary for activity (about 0.2, gram of water per gram of protein). In order to gain insights into the, role of water in the stability and the plasticity of the protein molecule, and the geometrical basis for the loss of activity that accompanies, dehydration, the crystal structures of monoclinic lysozyme with solvent, ...
