Protein Footprinting: Auxiliary Engine To Power The Structural Biology Revolution, Mark R. Chance, Erik R. Farquhar, Sichun Yang, David T. Lodowski, Janna G. Kiselar

Faculty Scholarship

Structural biology is entering an exciting time where many new high-resolution structures of large complexes and membrane proteins are determined regularly. These advances have been driven by over fifteen years of technology advancements, first in macromolecular crystallography, and recently in Cryo-electron microscopy. These structures are allowing detailed questions about functional mechanisms of the structures, and the biology enabled by these structures, to be addressed for the first time. At the same time, mass spectrometry technologies for protein structure analysis, “footprinting” studies, have improved their sensitivity and resolution dramatically and can provide detailed sub-peptide and residue level information for validating structures …
