Abstract: Diffraction-based structural biology methods are a fundamental tool 
for structural science, accounting for close to 85% of all macromolecular 
structures deposited to the Protein Data Bank. Recent advances in structural 
biology methods, from synchrotron, electron diffraction, and XFELs to 
computational advances and CryoEM, have opened the door to the investigation of 
more challenging target samples. This talk will highlight several research 
projects in the Bowman Lab on metalloprotein biology and the methods available 
to discover how structure contributes to their unique chemistry. Metals in 
proteins are ubiquitous (involving up to 50% of the proteome) and involved in 
many of the reactions that define life – transfer of energy, photosynthesis, 
metabolism, oxygen shuttling, and much more. In structural work, X-ray and 
electron sources used in diffraction and CryoEM studies can cause changes in 
oxidation state and radiation damage, obscuring the true nature of the role of 
the metal in the protein. We are working to make use of multiple methods, 
including spectroscopy coupled to diffraction data collection and specialized 
fixed-target platforms, to probe metalloprotein biology. This suite of 
approaches facilitates examination of protein structure and opens paths to 
further studies of protein dynamics and motion.
