NATE-1478
Description
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.
