Overview of Research
A main interest of S.Tsuda is to clarify mechanism of a new functional protein by utilizing the advanced techniques of molecular biology, biochemistry, and structural biology (NMR and X-ray). His current targets are the antifreeze proteins (fish AFPI~III, fish AFGP, and fungi hyperactive AFP), which have originally been discoveredd from Japanese organisms in the last 10 years.
