We report site-resolved observation of hydrogen exchange in the micro-crystalline protein Crh. Our approach is based on the use of proton T2' -selective 1H-13C-13C correlation spectra for site-specific assignments of carbons nearby labile protein protons. We compare the proton T2' selective scheme to frequency selective water observation in deuterated proteins, and discuss the impacts of deuteration on 13C linewidths in Crh. We observe that in micro-crystalline proteins, solvent accessible hydroxyl and amino protons show comparable exchange rates with water protons as for proteins in solution, and that structural constraints, such as hydrogen bonding or solvent accessibility, more significantly reduce exchange rates.

Quantification of protein backbone hydrogen-deuterium exchange rates by solid state N
Quantification of protein backbone hydrogen-deuterium exchange rates by solid state NMR spectroscopy
Abstract We present the quantification of backbone amide hydrogen-deuterium exchange rates (HDX) for immobilized proteins. The experiments make use of the deuterium isotope effect on the amide nitrogen chemical shift, as well as on proton dilution by deuteration. We find that backbone amides in the microcrystalline α-spectrin SH3 domain exchange rather slowly with the solvent (with exchange rates negligible within the individual 15Nâ??T 1 timescales). We observed chemical exchange for 6...

NMR on frozen solutions is an ideal method to study fundamental questions of macromolecular hydration, because the hydration shell of many biomolecules does not freeze together with bulk solvent. In the present study, we present previously undescribed NMR methods to study the interactions of proteins with their hydration shell and the ice lattice in frozen solution. We applied these methods to compare solvent interaction of an ice-binding...
