PRODUCTION OF FUCOSYLATED CARBOHYDRATES BY ENZYMATIC FUCOSYLATION SYNTHESIS OF SUGAR NUCLEOTIDES; AND IN SITU REGENERATION OF GDP-FUCOSE

摘要

This invention contemplates improved methods of enzymatic production of carbohydrates especially fucosylated carbohydrates. Improved syntheses of glycosyl 1- or 2-phosphates using both chemical and enzymatic means are also contemplated. The phosphorylated glycosides are then used to produce sugar nucleotides that are in turn used as donor sugars for glycosylation of acceptor carbohydrates. Especially preferred herein in the use of a disclosed method for fucosylation.
