摘要
We report here almost complete backbone assignment of a Ca2+-binding protein of the beta gamma-crystallin superfamily from Methanosarcina acetivorans, at two denaturant (GdmCl) concentrations, using double and triple resonance experiments. These NMR assignments will be useful to understand the unfolding path of this protein.
