标题 :Process for the enzymatic synthesis of 2-deoxy-β-D-galactosides
发明人：THIEM JOACHIM; WIEMANN TORSTEN
权利人:HOECHST AG
摘要:The invention relates to a process for the enzymatic synthesis of 2-deoxy- beta -D-galactosides. The enzyme galactosyltransferase is able to catalyze the transfer of 2-deoxygalactose residues from the donor substrate uridine 5'-diphospho-2-deoxy-D-galactose to N-acetylglucosamine or aspartyl-N-acetylglucosamine or, in the presence of lactose, to terminal glucose.

摘要:The invention relates to an enzymatic method for synthesizing oligosaccharides, whereby one saccharide group of a sucrose analogue each is transferred onto an acceptor molecule, for example for glycosylating a hydroxyl compound, a saccharide, peptide, or a drug. According to the inventive method, an enzymatic synthesis of β-D-fructofuranosyl-a-D-aldopyranoside is carried out in a first step, and in a second step one of the saccharide groups is enzymatically transferred onto the acceptor molecule.

标 题 :Genetically modified cells and methods for making activated sugar-nucleotides
发明人：BAR-PELED MAOR; YANG TING
权利人:UNIV GEORGIA
摘要:This disclosure generally relates to genetically engineered cells and methods of making and using such genetically engineered cells. Generally, the genetically engineered cells exhibit an increase in synthesis of an activated sugar-nucleotide compared to a wild type control. In some embodiments, the activated sugar-nucleotide produced by the genetically engineered cell is an activated sugar-nucleotide that is not natively synthesized by wild type, un-engineered cell. In some embodiments, the activated sugar-nucleotide is an activated uridine diphosphate sugar nucleotide. In other embodiments, the activated sugar-nucleotide is an activated cysteine monophosphate sugar nucleotide. In still other embodiments, the activated sugar-nucleotide is an activated guanosine diphosphate sugar nucleotide. In some embodiments, the activated sugar-nucleotide includes an isotopic label.
