Protein
Galactosylgalactosylxylosylprotein 3-beta-glucuronosyltransferase I
Organism
Drosophila melanogaster
Function
Involved in the biosynthesis of L2/HNK-1 carbohydrate epitope on both glycolipids and glycoproteins. Shows strict specificity for Gal-beta-1,3-Gal-beta-1,4-Xyl, exhibiting negligible incorporation into other galactoside substrates.
Similarity
Belongs to the glycosyltransferase 43 family.
