 108-322 9.40e-110

Beta-4-Galactosyltransferase is involved in the formation of the poly-N-acetyllactosamine core structures present in glycoproteins and glycosphingolipids; Beta-4-Galactosyltransferase transfers galactose from uridine diphosphogalactose to the terminal beta-N-acetylglucosamine residues, hereby forming the poly-N-acetyllactosamine core structures present in glycoproteins and glycosphingolipids. At least seven homologous beta-4-galactosyltransferase isoforms have been identified that use different types of glycoproteins and glycolipids as substrates. Of the seven identified members of the beta-1,4-galactosyltransferase subfamily (beta1,4-Gal-T1 to -T7), b1,4-Gal-T1 is most characterized (biochemically). It is a Golgi-resident type II membrane enzyme with a cytoplasmic domain, membrane spanning region, and a stem region and catalytic domain facing the lumen.

N-terminal region of glycosyl transferase group 7; This is the N-terminal half of a family of galactosyltransferases from a wide range of Metazoa with three related galactosyltransferases activities, all three of which are possessed by one sequence in some cases. EC:2.4.1.90, N-acetyllactosamine synthase; EC:2.4.1.38, Beta-N-acetylglucosaminyl-glycopeptide beta-1,4- galactosyltransferase; and EC:2.4.1.22 Lactose synthase. Note that N-acetyllactosamine synthase is a component of Lactose synthase along with alpha-lactalbumin, in the absence of alpha-lactalbumin EC:2.4.1.90 is the catalyzed reaction.
