Biological Properties
General Function Involved in galactosyltransferase activity
Specific Function Beta-1,3-N-acetylglucosaminyltransferase that plays a key role in the synthesis of lacto- or neolacto-series carbohydrate chains on glycolipids, notably by participating in biosynthesis of HNK-1 and Lewis X carbohydrate structures. Has strong activity toward lactosylceramide (LacCer) and neolactotetraosylceramide (nLc(4)Cer; paragloboside), resulting in the synthesis of Lc(3)Cer and neolactopentaosylceramide (nLc(5)Cer), respectively. Probably plays a central role in regulating neolacto-series glycolipid synthesis during embryonic development.
Pathways
  • Glycosphingolipid biosynthesis - lacto and neolacto series
  • protein glycosylation
Reactions
Uridine diphosphate-N-acetylglucosamine + beta-D-galactosyl-(1->4)-beta-D-glucosyl-(1<->1)-ceramide → Uridine 5'-diphosphate + N-acetyl-beta-D-glucosaminyl-(1->3)-beta-D-galactosyl-(1->4)-beta-D-glucosyl-(1<->1)-ceramide details
