Abstract

The invention relates to an improved process for enzymically galactosylating monosaccharides and oligosaccharides, with in-situ regeneration of the nucleotide sugar (or of the nucleoside diphosphate sugar), in the presence of sucrose synthase, .beta.-1-4-galactosyl transferase and uridine diphosphate-glucose 4'-epimerase, (UDP-glucose 4'-epimerase), in which process the uridine diphosphate-glucose 4'-epimerase is reactivated with a ketosugar derivative.
