Research Description |
We use X-ray crystallography to study the three-dimensional structures of proteins. The structural information is used for drug design, protein engineering, to understand catalytic mechanisms, and to explore protein evolution. Our group is also involved in the development of tools and techniques associated with synchrotron radiation, especially multiple wavelength anomalous diffraction (MAD). Our main projects include studies of enzymes involved in purine nucleotide metabolism and pyrimidine nucleotide metabolism, studies of enzymes involved in co-factor biosynthesis, especially thiamin biosynthesis, and enzymes involved in polyamine biosynthesis. more |
