Abstract
The present invention relates to nucleotide-sugar-synthesizing enzymes (enzymes with nucleotidyltransferase or pyrophosphorylase activity) from nonparasitic protists, to a process for the preparation thereof and to the use thereof for preparing nucleotide-sugars. The enzymes according to the invention make possible or greatly simplify the enzymatic preparation of various nucleotide-sugars on the industrial scale from low-cost precursors. It is possible with the aid of the discovered enzymes to prepare, for example, GDP-fucose, GDP-mannose, UDP-glucose, UDP-glucosamine, UDP-galactose, UDP-galactosamine, UDP-N-acetylglucosamine and UDP-N-acetylgalactosamine in economic quantities.
