Yan Kung

In the Kung lab, our aim is to gain molecular insight into the function of enzymes by determining and examining their three-dimensional structures. By studying enzyme structures using X-ray crystallography while interrogating their functions with complementary biochemical techniques, we can develop a chemical understanding of enzyme catalysis. Enzyme systems of particular interest in the Kung lab include those that are involved in producing molecules that are useful to society, such as drug or biofuel compounds. Armed with a deep awareness of how an enzyme’s structure dictates its function, we may even engineer the enzyme in order to alter its function, allowing us to design modified enzymes that are tailor-made to produce more desirable drugs or biofuels.
