| Outline of Final Research Achievements |
As part of chemical study on glycoconjugate in the cell wall component of mycobacteria, oligoarabinofuranosides has been synthesized in order to use as the probe with fragment structure of the arabinan which is the outmost glycan of cell wall glycoconjugate.
For the analysis of the novel hydrolases of arabinan, label-free ESI Mass analysis of the products degraded by the enzyme has been carried out. Furthermore, for the development of general methodology toward synthesis of the 1.2-cis glycosidic linkages, intramolecular aglycon delivery (IAD) has been examined. The syntheses and structural analysis of oligosaccharides found in hydrophilic motif of HRGP, various plant polysaccharides and oligosaccharide-modified structure of marine toxin have been demonstrated. On the other hand, based on the study on glycan modification process of bacterial N-linked glycoprotein by chemical and enzymatic techniques, substrate specificity of the key oligosaccharyl transferase could be suggested.
