  名称：

  Enzymic transfer of 6-modified d-galactosyl residues: synthesis of biantennary penta- and hepta-saccharides having two 6-deoxy-d-galactose residues at the nonreducing end and evaluation of 6-deoxy-d-galactosyl transfer to glycoprotein using bovine β-(1 → 4)-galactosyltransferase and UDP-6-deoxy-d-galactose

  摘要：

  UDP-6-Deoxy-D-galactose and UDP-6-deoxy-6-fluoro-D-galactose were synthesized and their transfer to 2-acetamido-2-deoxy-D-glucose (N-acetyl-D-glucosamine) by beta-(1 --> 4)galactosyltransferase was examined. The transfer rates of 6-deoxy-D-galactose and 6-deoxy-6-fluoro-D-galactose were 1.3 and 0.2% of that of D-galactosyl transfer, respectively. The 2-acetamido-4-O-(6-deoxy-beta-D-galactopyranosyl)-2-deoxy-D-glucopyranose (6'-deoxy-N-acetyllactosamine) and methyl 2-acetamido-4-O-(6-deoxy-6-fluoro-beta-D-galactopyranosyl)-2-deoxy-D-glucopyranoside (6'-deoxy-6'-fluoro-N-acetyllactosamine) were synthesized enzymatically in 30 and 59% yields, respectively. Further, 6-deoxy-D-galactose could be completely transferred to N-linked type biantennary oligosaccharides having two N-acetyl-D-glucosaminyl residues at the nonreducing end to give the corresponding penta- and hepta-saccharides in 55 and 57% yields, respectively. An assay of 6-deoxy-D-galactosyl transfer using asialo agalacto alpha(1)-acid glycoprotein as an acceptor suggested that 6-deoxy-D-galactose was transferred to about 30% of the N-acetyl-D-glucosaminyl residues in the N-linked oligosaccharides of the glycoprotein.
