Biochem/physiol Actions
β-1,4-Galactosyl Transferase catalyzes the transfer of galactose from UDP-galactose to the terminal N-acetylglucosamine residues on elongating oligosaccharide chains. It is also considered to be a biosynthetic enzyme of the Golgi apparatus. β-1,4-Galactosyl Transferase can also be found on the cell surface functioning as a cell-adhesion molecule during various cellular interactions by binding to N-acetylglucosamine containing oligosaccharide substrates or ligands in the extracellular matrix.
Other Notes
1 U corresponds to the amount of enzyme which transfers 1 μmol galactose from UDP-galactose to N-Acetyl-D-glucosamine per minute at pH 7.4 and 37°C in the presence of α-Lactalbumin
