Biological Properties
General Function Involved in galactosylgalactosylxylosylprotein 3-beta-glucuronosyltransferase activity
Specific Function Glycosaminoglycans biosynthesis. Involved in forming the linkage tetrasaccharide present in heparan sulfate and chondroitin sulfate. Transfers a glucuronic acid moiety from the uridine diphosphate-glucuronic acid (UDP-GlcUA) to the common linkage region trisaccharide Gal-beta-1,3-Gal-beta-1,4-Xyl covalently bound to a Ser residue at the glycosaminylglycan attachment site of proteoglycans. Can also play a role in the biosynthesis of l2/HNK-1 carbohydrate epitope on glycoproteins. Shows strict specificity for Gal-beta-1,3-Gal-beta-1,4-Xyl, exhibiting negligible incorporation into other galactoside substrates including Galbeta1-3Gal beta1-O-benzyl, Galbeta1-4GlcNAc and Galbeta1-4Glc.
Pathways
  • Glycosaminoglycan biosynthesis - chondroitin sulfate / dermatan sulfate
  • Glycosaminoglycan biosynthesis - heparan sulfate / heparin
  • protein glycosylation
