Abstract
Amide hydrogen/deuterium exchange mass spectrometry is rapidly becoming a powerful method for high-resolution analyses of protein dynamics, structure, and function. Hydrogen/deuterium exchange approaches can provide information that greatly augments and refines information derived from high-resolution structural studies, and can provide detailed information on native protein structure when structural information is unavailable. Application of this method for rapid analyses of protein-ligand complexes could prove useful for studies of important disease-related protein complexes. The following review covers fundamentals of hydrogen/deuterium exchange and its applications to the study of protein-ligand complexes. In addition, hydrogen/deuterium exchange mass spectrometry studies on a protein-inhibitor complex are presented.
