Characterization of proteins and protein complexes is a major keystone of structural biology. As our understanding of cellular processes continues to evolve from simple pathways to complicated networks, our need for advanced analytical methods is quite apparent. Mass spectrometry (MS)-based structural approaches can be used to study protein conformational changes and dynamics, protein motion/flexibility, ligand-protein binding, and protein-protein interfaces.

The origin of hydrogen-deuterium exchange (HDX) dates back to the 1950s, when protein scientist Linderstrøm-Lang created a method involving protein deuteration to distinguish amide hydrogens participating in secondary structures. Today, scientists frequently rely on HDX data to investigate protein structure, conformational dynamics, and protein-ligand interaction.
