Application

Kojibiose, a disaccharide product of glucose caramelization and an inhibitor of plant glucosidase I, may be used to help identify and characterize glucosidase I enzymes involved in terminal deglycosylation of high-mannose oligosaccharides. Kojibiose may be used as a substrate to study the biological species, enzymes and catabolic processes that catabolize it as an energy source. Kojibiose may be used to identify, differentiate and characterize kojibiose phosphorylase(s) (KP).

Biochem/physiol Actions

Kojibiose is an inhibitor of plant glucosidase I. It inhibits the removal of terminal glucose from the high-mannose oligosaccharide (Glc)3(Man)9(GlcNAc)2, either from the free oligosaccharide or from the oligosaccharide attached to a protein via N-linkage.

Glycoside hydrolase (GH) family 65 contains phosphorylases acting on maltose (Glc-α1,4-Glc), kojibiose (Glc-α1,2-Glc), trehalose (Glc-α1,α1,-Glc), and nigerose (Glc-α1,3-Glc). These phosphorylases can efficiently catalyze the reverse reactions with high specificities, and thus can be applied to the practical synthesis of α-glucosyl
