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 (Glc)3(Man)9(GlcNAc)2.
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
