Biological Properties
General Function Involved in galactoside 2-alpha-L-fucosyltransferase activity
Specific Function Creates a soluble precursor oligosaccharide FuC-alpha ((1,2)Galbeta-) called the H antigen which is an essential substrate for the final step in the soluble A and B antigen synthesis pathway. H and Se enzymes fucosylate the same acceptor substrates but exhibit different Km values.
Pathways
  • Glycosphingolipid biosynthesis - globo and isoglobo series
  • Glycosphingolipid biosynthesis - lacto and neolacto series
  • protein glycosylation
