چکیده انگلیسی
Conformational changes and protein dynamics play an important role in the catalytic efficiency of enzymes. Amide H/D exchange mass spectrometry (H/D exchange MS) is emerging as an efficient technique to study the local and global changes in protein structure and dynamics due to ligand binding, protein activation-inactivation by modification, and protein-protein interactions. By monitoring the selective exchange of hydrogen for deuterium along a peptide backbone, this sensitive technique probes protein motions and structural elements that may be relevant to allostery and function. In this report, several applications of H/D exchange MS are presented which demonstrate the unique capability of amide hydrogen/deuterium exchange mass spectrometry for examining dynamic and structural changes associated with enzyme catalysis.
