Effect of an Intrinsically Disordered Plant Stress Protein on the Properties of Water

Dehydrins are plant proteins that are able to protect plants from various forms of dehydrative stress, such as drought, cold, and high salinity. Dehydrins can prevent enzymes from losing activity after freeze/thaw treatments. Previous studies had suggested that the dehydrins function by a molecular shield effect, essentially preventing a denatured enzyme from aggregating with another enzyme. Therefore, the larger the dehydrin, the larger the shield and theoretically the more effective the protection.
