Lab Description
Our lab studies biological and soft matter systems using high pressure and X-ray techniques. A high-pressure cryocooling method was developed for crystal cryoprotection in macromolecular crystallography. In addition, the method was successfully applied to stabilize ligand-protein interactions, to study the pressure effect on the structure, and to entrap an intermediate enzymatic state. Using the high-pressure method, we will study the phase behaviors of glassy water, water-protein interactions, and protein functions and dynamics at cryogenic temperatures.
