ENZYME entry: EC

Accepted Name
N-acetyl-beta-D-glucosaminide beta-(1,3)-galactosyltransferase.
Alternative Name(s)
Glucosaminylgalactosylglucosylceramide 4-beta-galactosyltransferase.
Glucosaminylgalactosylglucosylceramide beta-galactosyltransferase.
Lactotriaosylceramide 4-beta-galactosyltransferase.
Paragloboside synthase.
Reaction catalysed
UDP-alpha-D-galactose + N-acetyl-beta-D-glucosaminyl-R <=> UDP + beta-D-galactosyl-(1->3)-N-acetyl-beta-D-glucosaminyl-R
  • The enzyme transfers galactose from UDP-alpha-D-galactose to the 3-position of substrates with a non-reducing terminal N-acetyl-beta- D-glucosamine (beta-GlcNAc) residue.
  • It can act on both glycolipids and glycoproteins, generating a structure known as the type 1 histo-blood group antigen precursor.
