| Outline of Final Research Achievements |
This study focuses on enzymes belonging to glycoside hydrolase family 131, CcGH131A and CcGH131B, from a basidiomycete, Coprinopsis cinerea. A heterologous expression system of CcGH131A using Pichia pastoris was constructed, and the crystal structure of CcGH131A in a complex with ligand was determined. The cDNA of CcGH131B was cloned, and a heterologous expression system of CcGH131A using Escherichia coli was constructed. The protein was crystallized and the structure was determined. An experiment using fluorescence spectroscopy was performed to analyze the interaction between the proteins and polysaccharides. The results suggest that the substrate specificities of CcGH131A and CcGH131B are expected to be markedly different.
