PROCESS FOR ENZYMICALLY GALACTOSYLATING MONOSACCHARIDES AND OLIGOSACCHARIDES

摘要

The invention concerns an improved method for the enzymatic galactosylation of monosaccharides and oligosaccharides with in situ regeneration of the nucleotide sugar (or the nucleoside diphosphate sugar) in the presence of saccharose synthase, .beta.-1-4-galactosyl transferase and uridine diphosphate glucose-4'-epimerase (UDP glucose-4'-epimerase), the method calling for the uridine diphosphate glucose-4'-epimerase to be reactivated by a ketone sugar derivative.
