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).

Packaging

1 mg in glass bottle

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.
