X-ray crystallography is one of the most powerful tools to examine protein structure at atomic detail. My laboratory uses single crystal x-ray diffraction techniques to determine the three-dimensional structure of biologically important proteins. Knowledge of the atomic resolution structure provides tremendous insight into understanding how the protein functions. Hypotheses on structure - function relationships can be drawn from the crystal structure, which can be tested using crystallography and other biophysical and biochemical techniques. Currently, the laboratory is focusing on enzymes in the biologically important pathways of RNA editing, sulfate activation, and glycobiology.
