NMR assignments of the intrinsically disordered K2 and YSK2 dehydrins

Dehydrins are proteins expressed by plants during various dehydrative stresses (drought, cold, and high salinity) to reduce cellular damage. These intrinsically disordered proteins are thought to function by binding to proteins to prevent denaturation, and to membranes to prevent leakage. Here, we report the H-1, N-15, and C-13 chemical shift assignments of the K-2 and YSK2 dehydrins from Vitis riparia (wild grape). Our results show that the segmental nature of dehydrins allows for the assignments of the shorter dehydrins to be used in that of the longer forms.
