生化/生理作用
β-1,4-Galactosyl Transferase catalyzes the transfer of galactose from UDP-galactose to the terminal N-acetylglucosamine residues on elongating oligosaccharide chains.[1][2] It is also considered to be a biosynthetic enzyme of the Golgi apparatus.[3] 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.[4]
组分

单位定义
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

Microarray technology has received considerable attention for rapid analysis of biomolecular interactions and high-throughput screening to identify binding partners. An efficient and selective immobilization technique of substances on the surface is essential for successful construction of microarrays. Although a variety

Many different theories have been advanced concerning the biological roles of the oligosaccharide units of individual classes of glycoconjugates. Analysis of the evidence indicates that while all of these theories are correct, exceptions to each can also be found. The

Two bacterial beta1-4-galactosyltransferases, NmLgtB and Hp1-4GalT, exhibit promiscuous and complementary acceptor substrate specificity. They have been used in an efficient one-pot multienzyme system to synthesize LacNAc, lactose, and their derivatives including those containing negatively charged 6-O-sulfated GlcNAc and C2-substituted GlcNAc
