专利号:US-2023407357-A1 优先权日:2022-05-20 标 题 :Biomanufacturing of oligosaccharides and derivatives from simple sugar 发明人:HOEPKER ALEXANDER CHRIS; CORGIE STEPHANE CEDRIC; SAVINO KEITH 权利人:ZYMTRONIX CATALYTIC SYSTEMS INC 摘要:The invention provides methods for glycosylation and preparation of compounds. The compounds include galactosylated, sialylated, fucosylated, and N-acetylglucosaminylated compounds from simple animal-derived, plant-derived, or microbe-derived oligosaccharides and sugars. In certain embodiments, the invention provides trinucleotide-free enzymatic production of oligosaccharides starting from simple sugars that include plant-based sugars. The invention also provides the enzymatic production of fucosylated oligosaccharides and fucosylated antibody-glycan conjugates from common sugars. The production may be a cell-free, one-pot synthesis using enzymes, and in some embodiments, immobilized enzymes. The synthesis is a highly customizable and highly efficient cell-free manufacturing process. In some embodiments, lactose derivatives and human milk oligosaccharides (HMOs) are produced.
