标 题 :Combined use of β-galactosidase and sialyltransferase coupled with in situ regeneration of CMP-sialic acid for one pot synthesis of oligosaccharides

摘要:A single reaction vessel process for the synthesis of a sialylated galactoside is disclosed. The synthesis utilizes a β-galactosidase to catalyze the reaction of a galactose-containing substrate and an acceptor to form a new galactosyl glycoside that is then sialylated using a cyclic multienzyme synthesis system to form CMP-sialic acid that sialylates the formed galactosyl glycoside in the presence of an α-sialyltransferase. The value of K m /V max for the formed galactosyl glycoside as a substrate for the α-sialyltransferase is less than one-third the K m /V max value for the galactose-containing substrate for that α-sialyltransferase.

摘要:A process for synthesizing oligonucleotides by phosphoramidite chemistry wherein the improvement is the use of substituted aryl carboxylic acids as the activators. These activators produce in situ nucleotide intermediates in which the substituted arylcarbonyl group has displaced the amidite moiety.
