Our lab studies biological and soft matter systems using high pressure and X-ray techniques.
A novel high pressure technique, called high pressure cryocooling, has been developed for biophysical and X-ray science. The method was primarily developed for crystal cryoprotection in macromolecular crystallography. It was revealed that the underlying physics involves interesting phase behaviors of glassy water at low temperatures.
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.
Our research paper was selected for the cover image in the Journal of International Union of Crystallography (IUCrJ).
Congratulations to Jin Kyun Kim and Prof. Chae Un Kim whose research image appear on the cover of the January 2018 edition of IUCrJ.
The image indicates the ultrahigh-resolution (0.9 Å) crystal structure of 7.0 atm CO2 hCA II (human Carbonic Anhydrase II). A closer view of the active site (Zn, CO2 binding site and His64) is shown through the entrance conduit with a 2Fo – Fc map (in blue) contoured at 2.5σ (for His64) and 5.0σ (others). The isolated electron density of the C atom of CO2 is clearly visible in this ultrahigh-resolution structure.
