Biosynthesis of blood-group I and i substances. Specificity of bovine colostrum beta-N-acetyl-D-glucosaminide beta 1 leads to 4 galactosyltransferase.
Blanken W.M., Hooghwinkel G.J., Van Den Eijnden D.H.
Highly purified bovine colostrum beta-N-acetylglucosaminide beta 1 leads to 4 galactosyltransferase was used to investigate the galactosylation of the synthetic, branched trisaccharide GlcNAcbeta 1 leads to 3(GlcNAcbeta 1 leads to 6)Gal, which is the branching point in blood-group I antigenic stru ... >> More
Highly purified bovine colostrum beta-N-acetylglucosaminide beta 1 leads to 4 galactosyltransferase was used to investigate the galactosylation of the synthetic, branched trisaccharide GlcNAcbeta 1 leads to 3(GlcNAcbeta 1 leads to 6)Gal, which is the branching point in blood-group I antigenic structures. Two galactose residues could readily be incorporated from UDP-galactose into the trisaccharide, yielding a pentasaccharide with the following structure: Galbeta 1 leads to 4GlcNAcbeta 1 leads to 3(Galbeta 1 leads to 4GlcNAcbeta 1 leads to 6)Gal. From a partially completed incubation an intermediate tetrasaccharide was isolated, the structure of which was investigated by use of an acetolysis method, involving high-pressure liquid chromatography and double labelling techniques. It appeared that this intermediate consisted for more than 95% of one of two possible structures: GlcNAcbeta 1 leads to 3(Galbeta 1 leads to 4GlcNAcbeta 1 leads to 6)Gal. This reveals that the enzymatic galactosylation of the trisaccharide proceeds in a highly preferred order, in which the 1 leads to 6-linked N-acetylglucosamine residue is galactosylated first and thus that the galactosyltransferase displays a high degree of 'branch specificity'. Kinetic data suggest that galactosylation of the 1 leads to 6-linked N-acetylglucosamine in the trisaccharide enhances the acceptor properties of the 1 leads to 3-linked N-acetylglucosamine residue. << Less

Biosynthesis of terminal Gal alpha 1----3Gal beta 1----4GlcNAc-R oligosaccharide sequences on glycoconjugates. Purification and acceptor specificity of a UDP-Gal:N-acetyllactosaminide alpha 1----3-galactosyltransferase from calf thymus.

A UDP-Gal:Gal beta 1----4GlcNAc-R alpha 1----3- and a UDP-Gal:GlcNAc-R beta 1----4-galactosyltransferase have been purified 44,000- and 101,000-fold, respectively, from a Triton X-100 extract of calf thymus by affinity chromatography on UDP-hexanolamine-Sepharose and alpha-lactalbumin-Sepharose in ... >> More
A UDP-Gal:Gal beta 1----4GlcNAc-R alpha 1----3- and a UDP-Gal:GlcNAc-R beta 1----4-galactosyltransferase have been purified 44,000- and 101,000-fold, respectively, from a Triton X-100 extract of calf thymus by affinity chromatography on UDP-hexanolamine-Sepharose and alpha-lactalbumin-Sepharose in a yield of 25-40%. Sodium dodecyl sulfate gel electrophoresis under reducing conditions revealed a major polypeptide species with a molecular weight of 40,000 and a minor form at Mr 42,000 for the alpha 1----3-galactosyltransferase and a major polypeptide with Mr 51,000 for the beta 1----4-galactosyltransferase. Analytical gel filtration on Sephadex G-100 yielded a monomeric form for each of the galactosyltransferases with Mr 43,000 and 59,000 respectively, in addition to peaks of activity at higher molecular weights. Isoelectric focussing of the alpha 1----3-galactosyltransferase revealed a significant charge heterogeneity with forms varying in pI values between 5.0 and 6.5. Acceptor specificity studies indicated that the purified alpha 1----3-galactosyltransferase was free from contaminating galactosyltransferase activities such as those involved in the synthesis of Gal beta 1----4GlcNAc-R and Gal beta 1----3GalNAc-R sequences, the blood group B determinant, the Pk antigen, trihexosylceramide, and ganglioside GM1. The alpha 1----3-galactosyltransferase appeared to be highly active with glycoproteins, oligosaccharides, and glycolipids having a terminal Gal beta 1----4GlcNAc beta 1----unit such as asialo-alpha 1-acid glycoprotein (Km = 1.25 mM), Gal beta 1----4GlcNAc beta 1----2Man alpha 1----3Man beta 1----4GlcNAc (Km = 0.57 mM), and paragloboside. The action of the alpha 1----3-galactosyltransferase was found to be mutually exclusive with that of the NeuAc:Gal beta 1----4GlcNAc-R alpha 2----6-sialyltransferase from bovine colostrum. In addition alpha 1----3-fucosylation of the N-acetylglucosamine residue in the preferred disaccharide acceptor structure completely blocked galactosylation of the alpha 1----3-galactosyltransferase. << Less
