Synthesis and enzymatic evaluation of mucin type core 4 O-glycan
Carbohydrate Letters
|August 17, 2001
Abstract:
Lactosylaminylated core-4 tetrasaccharide found in mucin type O-glycans has been synthesized . The non-reducing galactose residue of the deblocked tetrasaccharide was removed by beta-galactosidase from E. coli to produce the corresponding GlcNAc terminated compound. The core-2 and core-4 tetrasaccharides were evaluated as acceptors for the beta-1,3-N-acetylglucosaminyltransferase (iGnT), beta-1,4-Galactosyltransferase IV(beta4GalTIV) and beta-1,4-Galactosyltransferase I(beta4GalTI).
