Transglycosylation reaction of Mucor hiemalis endo-β-N-acetylglucosaminidase using sugar derivatives modified at C-1 or C-2 as oligosaccharide acceptors

We investigated the transglycosylation reaction of the recombinant endo-β-N-acetylglucosaminidase from Mucor hiemalis (Endo-M) expressed in Candida boidinii using such sugar derivatives as N-acylated d-glucosamines, C-glucosyl derivatives, and a 2-O-glycosylated disaccharide as acceptors. We found that a variety of sugar derivatives modified at C-1 or C-2 could be used as acceptors for transglycosylation by Endo-M to create novel oligosaccharides.
