| Outline of Final Research Achievements |
This project aims at identification and application of structural elements that regulate and improve the carbohydrase-catalyzed transfer activities by elucidating four promising phenomena, which we newly found. Results obtained are as follows: 1) we identify the structural elements to control the α-1,3-transfer reaction displayed by α-1,3-glucoside-transfer enzyme; 2) we reveal the reaction mechanism of the catalytic residue-mutated glycosidase that shows the high transfer yield; 3) a pore canal at the active site of glycosidase plays a role that supplies the catalytic water by study at the molecular level. 4) we analyze the polysaccharide-producing enzyme and identify its structural elements to contribute to the synthesis of oligosaccharides.
