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.
