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.

The kojibiose phosphorylase (KP) gene and trehalose phosphorylase (TP) gene from Thermoanaerobacter brockii ATCC35047 were intracellularly hyper-expressed under the control of the Bacillus amyloliquefaciens alpha-amylase promoter in Bacillus subtilis. The production yields were estimated to be 2.1 g of KP

The glucosyl transfer reaction of kojibiose phosphorylase (KP; EC 2.4.1.230) was examined using glycerol or myo-inositol as an acceptor. In the case of glycerol, KP produced two main transfer products: saccharides A and B. The structure of saccharide A was
