A method for the enzymatic synthesis galactosyl adhesive glycoprotein - building blocks

摘要

the synthesis of gal - (14) - glcnac - (in) - asn and gal - (14) - glcnac - (14) - glcnac - (1 - (n) - l - asn from precursors aspartyl - n - acetylglucosamin or aspartylchitobiosylamin in the presence of a galaktosyldonors in vitro with the help of galaktosyltransferase are carried out. the galactosyldonor udp gal can in situ from udp glc under catalysis of udp galactose 4 epimerase can be synthesized.
