An approach for enzymatic sythesis of oligosachcharides via transglycosylation with endo-beta-1,3-glucanase from Oerskovia xanthineolytica is described.Linear -beta-1,3-glucan (laminarin) was used as a donor of glycosyl residues, whereas nitrophenyl glycosides of different monosaccharides served as acceptors.The synthesis was performed in water-organic solvent environment with several combinations of donor/acceptor.Employing p-nitrophenyl-beta-D-xylopyranoside as an acceptor in the presence of 30% acetonitrile resulted in the production of six new glycosides shown by FAB MS to be di-, tri- and tetrasaccharides.This enzyme is therefore suitable for the synthesis of short-chain oligosaccharides.
