Biological Activity

[Description]:

Terminal N-acetyl-β-D-glucosaminyl residues in polysaccharides, glycoproteins and glycopeptides can act as acceptor. High activity is shown towards such residues in branched-chain polysaccharides when these are linked by β-1,6-links to galactose residues; lower activity towards residues linked to galactose by β-1,3-links. A component of EC 2.4.1.22 (lactose synthase). Reaction: UDP-α-D-galactose + N-acetyl-β-D-glucosaminylglycopeptide = UDP + β-D-galactosyl-(1→4)-N-acetyl-β-D-glucosaminylglycopeptide
