The Structural Biophysics Laboratory (SBL) focuses on solution structural biology and biophysics aimed at understanding and regulating the mechanism of action of proteins and nucleic acids. The major structural tool for the SBL is nuclear magnetic resonance (NMR) spectroscopy, and the Laboratory has a very strong interdisciplinary approach to understanding biochemical and biological mechanisms. Technologies incorporated in the research program include solution X-ray scattering, fluorescence and circular dichroism spectroscopy, mass spectrometry, calorimetry and novel binding methodologies including SPR and microscale thermophoresis. Research in the Byrd laboratory (Macromolecular NMR Section) focuses on protein-protein interactions in the ubiquitin-proteasome regulation pathway and the area of ADP-ribosylation factor (Arf) family of GTP-binding proteins and their regulators, the Arf GTPase-activating proteins (Arf GAPs). We seek to provide detailed structural and mechanistic insight, which we combine with collaborations in molecular and cell biology to inform and modulate biological function
