Enzymes are bio-based catalysts that play critical roles in many biological processes. A huge number of enzymes have been found and widely used in food, chemical, and biomedical industries. Most of enzymes are proteins, which consist of large and complicated molecular structures. Therefore, structure and function of many enzymes remain unknown.
We are studying the structure and function of enzymes by using X-ray crystallography, protein engineering, and various biochemical techniques. We are mainly focusing on interesting enzymes in aspects of biology and bio-industry.
