 134-352 2.15e-127

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.

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.

 139-289 1.26e-03

Glycosyltransferase family A (GT-A) includes diverse families of glycosyl transferases with a common GT-A type structural fold; Glycosyltransferases (GTs) are enzymes that synthesize oligosaccharides, polysaccharides, and glycoconjugates by transferring the sugar moiety from an activated nucleotide-sugar donor to an acceptor molecule, which may be a growing oligosaccharide, a lipid, or a protein. Based on the stereochemistry of the donor and acceptor molecules, GTs are classified as either retaining or inverting enzymes. To date, all GT structures adopt one of two possible folds, termed GT-A fold and GT-B fold. This hierarchy includes diverse families of glycosyl transferases with a common GT-A type structural fold, which has two tightly associated beta/alpha/beta domains that tend to form a continuous central sheet of at least eight beta-strands. The majority of the proteins in this superfamily are Glycosyltransferase family 2 (GT-2) proteins. But it also includes families GT-43, GT-6, GT-8, GT13 and GT-7; which are evolutionarily related to GT-2 and share structure similarities.
