Abstract
The invention provides a mutant enzyme having trans-sialidase activity (EC 3.2.1.18), characterized by an enhanced trans-sialidase:sialidase ratio when compared to its parent sialidase enzyme. Further the enzyme may be used in a method for trans-sialylating mono- and oligo-saccharides, including galacto-oligosaccharides (GOS), fructo-oligosaccharides (FOS), malto-oligosaccharides (MOS), isomalto-oligosaccarides (IMO), lactulose, melibiose, maltose, glycosyl sucrose, lactosucrose and fucose. Trans-sialidated mono- and oligo-saccharides, produced with the mutant enzyme, are useful in preparing infant formula, a prebiotic nutritional supplement, and a food supplement.
