Phosphorylation and sulfation of oligosaccharide substrates critically influence the activity of human beta1,4-galactosyltransferase 7 (GalT-I) and beta1,3-glucuronosyltransferase I (GlcAT-I) involved in the biosynthesis of the glycosaminoglycan-protein linkage region of proteoglycans.

Abstract excerpt

We determined whether the two major structural modifications, i.e. phosphorylation and sulfation of the glycosaminoglycan-protein linkage region (GlcAbeta1-3Galbeta1-3Galbeta1-4Xylbeta1), govern the specificity of the glycosyltransferases responsible for the biosynthesis of the tetrasaccharide primer. We analyzed the influence of C-2 phosphorylation of Xyl residue on human beta1,4-galactosyltransferase 7...
