Sugar chains confer functionality to many organic molecules in glycosides. Enzymes like glycosyltransferases catalyze the synthesis of these chains in various biological systems. However, the commercial production of carbohydrate chains involving enzymes that are associated with β-1,2-glucan, a polysaccharide, poses technical challenges. Now researchers from Tokyo University of Science and Niigata University have been able to structurally and functionally identify a novel enzyme that catalyzes the easy formation of glycosidic bonds in β-1,2-glucooligosaccharide glycosides.
