Abstract
We evaluated the stabilities of kojibiose and sophorose when heated under neutral pH conditions. Kojibiose and sophorose epimerized at the C-2 position of glucose on the reducing end, resulting in the production of 2-O-α-D-glucopyranosyl-D-mannose and 2-O-β-D-glucopyranosyl-D-mannose, respectively. Under weak alkaline conditions, kojibiose was decomposed due to heating into its mono-dehydrated derivatives, including 3-deoxy-2,3-unsaturated compounds and bicyclic 3,6-anhydro compounds. Following these experiments, we propose a kinetic model for the epimerization and decomposition of kojibiose and sophorose by heat treatment under neutral pH and alkaline conditions. The proposed model shows a good fit with the experimental data collected in this study. The rate constants of a reversible epimerization of kojibiose at pH 7.5 and 90 °C were (1.6 ± 0.1) × 10-5 s-1 and (3.2 ± 0.2) × 10-5 s-1 for the forward and reverse reactions, respectively, and were almost identical to those [(1.5 ± 0.1) × 10-5 s-1 and (3.5 ± 0.4) × 10-5 s-1] of sophorose. The rate constant of the decomposition reaction for kojibiose was (4.7 ± 1.1) × 10-7 s-1 whereas that for sophorose [(3.7 ± 0.2) × 10-6 s-1] was about ten times higher. The epimerization reaction was not significantly affected by the variation in the buffer except for a borate buffer, and depended instead upon the pH value (concentration of hydroxide ions), indicating that epimerization occurred as a function of the hydroxide ion. These instabilities are an extension of the neutral pH conditions for keto-enol tautomerization that are often observed under strong alkaline conditions.

Abstract
A major glycoprotein at the surface of calf thyroid cells, GP-3 (M(r) 20,000), contains the I-antigenic activity of calf thyroid which has been attributed to its poly-N-acetyllactosamine N-linked saccharide chains (Edge, A. S. B., and Spiro, R. G., J. Biol. Chem. 260, 15332-15338, 1985). The present study demonstrated that alkaline borohydride treatment of GP-3 results in the release of five neutral and five acidic saccharides that were found to represent over 30% of the saccharides of this carbohydrate-rich glycoprotein. Three of the oligosaccharides contained terminal alpha1 --> 3-linked galactose residues which accounted for their affinity toward Bandeiraea simplicifolia I lectin. The saccharides could be grouped into several distinct categories on the basis of their internal sequence. A novel tetrasaccharide in GP-3 was shown to have the structure: Gal alpha1 --> 3Gal beta1 --> 6(Gal beta1 --> 3)GalNAcH2. An unsubstituted N-acetylgalactosamine unit and a Gal beta1 --> 3GalNAc disaccharide were prominent O-linked constituents, with the disaccharide serving as a core unit for the attachment of sialic acid residues to form tetra- and trisaccharides. A branched core structure, Gal beta1 --> 3(GlcNAcbeta1 --> 6)GalNAcH2 was shared by 4 of the 10 saccharides, the most complete of which was assigned the sequence NeuAc alpha2 --> 3Gal beta1 --> 3(Gal alpha1 --> 3Gal beta1 --> 4GlcNAc beta1 --> 6)GalNAcH2.

Abstract
The oligosaccharide products resulting from treatment of mucin-type glycoproteins with alkali in the presence of the sulfite anion have been investigated. Treatment of fetuin and of tryptic glycopeptides from the human erythrocyte with this reagent resulted in the release of sulfited oligosaccharides identified as N-acetylsulfohexosamine (HexNAcSO3), alpha-NeuAc-(2----6)-HexNAcSO3, and alpha-NeuAc-(2----3)-Gal-(1----3 or 4)-[GlcNAc-(1----6)]-HexNAcSO3. In addition, 2.7 moles of sialic acid were released per mole of alpha-NeuAc-(2----6)-HexNAcSO3 from fetuin. The sulfohexosamine moiety is formed via unsaturated intermediates from a 3-O-substituted 2-acetamido-2-deoxy-D-galactosyl residue at the carbohydrate-peptide linkage site when this residue is not substituted at O-4 by another sugar residue. A reaction mechanism accounting for the release of the sulfited oligosaccharides from a 3-O- and 6-O-substituted hexosamine is proposed in which the oligosaccharide branch attached to O-6 is obtained as a specific fragment terminating in sulfohexosamine.

Abstract
Human milk beta-N-acetylglucosaminide beta 1 leads to 4-galactosyltransferase (EC 2.4.1.38) was used to galactosylate ovine submaxillary asialomucin to saturation. The major [14C]galactosylated product chain was obtained as a reduced oligosaccharide by beta-elimination under reducing conditions. Analysis by Bio-Gel filtration and gas-liquid chromatography indicated that this compound was a tetrasaccharide composed of galactose, N-acetylglucosamine and reduced N-acetylgalactosamine in a molar ratio of 2:0.9:0.8. Periodate oxidation studies before and after mild acid hydrolysis in addition to thin-layer chromatography revealed that the most probable structure of the tetrasaccharide is Gal beta 1 leads to 3([14C]Gal beta 1 leads to 4GlcNAc beta 1 leads to 6)GalNAcol. Thus it appears that Gal beta 1 leads to 3(GlcNAc beta 1 leads to 6)GalNAc units occur as minor chains on the asialomucin. The potential interference of these chains in the assay of alpha-N-acetylgalactosaminylprotein beta 1 leads to 3-galactosyltransferase activity using ovine submaxillary asialomucin as an acceptor can be counteracted by the addition of N-acetylglucosamine.

Abstract
The results of subcellular fractionation of sheep mammary gland membranes indicate that N-acetylgalactosaminyl polypeptide transferase and galactosyl-N-acetylgalactosaminyl transferase, which are involved in the assembly of disaccharide units of kappa-casein, are localized chiefly in Golgi membranes. The glycosyltransferase activities incorporating N-acetyl [1-14C] galactosamine and [U-14C] galactose from uridine diphosphate N-acetyl [1-14C] galactosamine and uridine diphosphate [U-14C] galactose, respectively, were measured after membrane solubilization with Triton X-100 either with unglycosylated caseinomacropeptide, or with this polypeptide containing the N-acetylgalactosamine side chain residues (desialylated and degalactosylated caseinomacropeptide). Radioactive N-acetylgalactosamine was incorporated in the unglycosylated acceptor peptide, and the glycosidic bonds in the product were alkali labile, suggesting that they were linked to the hydroxyamino acid residues. In addition radioactive N-acetylgalactosamine was released after alpha N-acetyl-D-galactosaminidase treatment of labelled caseinomacropeptide. [U-14C] galactose was incorporated in the desialylated and degalactosylated acceptor peptide. Reductive alkaline treatment of [U-14C] galactose peptide resulted in the release of a major product, the chromatographic properties of which in TLC were identical with authentic galactosyl (1 leads to 3) N-acetylgalactosaminitol. The structure of the labelled disacchariditol determined after periodate oxidation (two equivalents) by gas liquid chromatography-mass spectrometry revealed that the [U-14C] galactose was linked to position C-3 on the N-acetylgalactosaminyl-residue. The anomery of the galactose, as determined by a chemical method, indicates unambiguously a beta configuration.

Abstract
In order to obtain a [14C]galactosyl-N-acetylgalactosaminyl-protein which would be useful as an acceptor in studies on the specificity of glycosyltransferases, a porcine submaxillary gland microsomal galactosyltransferase preparation was used for the galactosylation in vitro of N-acetylgalactosaminyl-protein (desialylated ovine submaxillary mucin). The newly formed oligosaccharide unit was obtained as a reduced disaccharide after alkaline borohydride treatment of the [14C]galactosyl-N-acetylgalactosaminyl-protein product and as glycopeptides by proteolytic digestion of the glycoprotein. The reduced disaccharide consisted of equimolar amounts of galactose and N-acetylgalactosaminitol and was characterized by thin-layer chromatography, high-voltage electrophoresis and gas-liquid chromatography. Periodate oxidation studies on the reduced disaccharide revealed that [14C]galactose was linked to position C-3 on the N-acetylgalactosaminyl residue. Digestion of the reduced disaccharide and the glycopeptides with galactosidases gave equivocal results as to the anomeric configuration of the [14C]galactose residue. Nuclear magnetic resonance of the reduced disaccharide, however, definitely indicated that the configuration was beta. The specificity of the porcine submaxillary gland galactosyltransferase thus can be defined as a uridine diphosphogalactose: alpha-D-N-acetylgalactosaminyl-protein beta 1 leads to 3 transferase activity.

Abstract
Two different galactosyltransferase activities have been found in normal sera from A and O donors. Galactosyltransferase A incorporated galactose from UDP-Gal into sialic-acid-free ovine submaxillary mucin (asialo-mucin), whereas galactosyltransferase B transferred galactose from UDP-Gal to free N-acetylglucosamine or N-acetylglucosamine-glycoproteins. Specificity, kinetic and stability differences permitted the distinction of the activity of galactosyltransferase A from that of galactosyltransferase B; the only substrate found for galactosyltransferase A was asialo-mucin, whereas galactosyltransferase B showed only low activity towards asialo-mucin and free N-acetyl-galactosamine, but had a main specificity for either free N-acetylglucosamine or N-acetylglucosamine-protein. Galactosyltransferase B was more stable on heat inactivation than galactosyltransferase A; galactosyltransferase B could be separated from galactosyltransferase A by affinity chromatography on N-acetylglucosamine-derivatized agarose. The products of both enzyme activities have been analyzed. The galactosyltransferase A product was cleaved from asialo-mucin by alkaline-borohydride treatment. The acceptor used to identify the galactosyltransferase B product was free N-acetylglucosamine. Periodate oxidation studies performed on the reduced disaccharides indicated the linkage type of the products. The anomeric configuration of the respective galactosyltransferase products were determined with specific galactosidases. Using these methods, galactosyltransferase A was found to form a Galbeta (1 leads to 3)GalNAc-protein linkage and galactosyltransferase B was found to form a Galbeta(1 leads to 4)GlcNAc-linkage.

Abstract
Apolipoprotein C-III1 and apolipoprotein C-III2 each contain one oligosaccharide side chain, bound O-glycosidically to threonine in position 74 of the amino acid sequence. The studies reported in this paper characterize these alkali labile oligosaccharides, thereby demonstrating the complete structure of apolipoprotein C-III. Monosaccharide analysis revealed the following sugar composition: D-galactose/N-acetyl-D-galactosamine/sialic acid 1 : 1 : 1 and 1 : 1 : 2 for apolipoprotein C-III1 and apolipoprotein C-III2, respectively. Treatment of desialylated apolipoproteins with alkaline borohydride released the reduced disaccharide beta-D-galactosyl-(1 leads to 3)-N-acetyl-D-galactosaminitol, which was detected by gas-liquid chromatography. Further studies employing periodate oxidation and Smith degradation indicated that the structure of the trisaccharide from apolipoprotein C-III1 was alpha-N-acetylneuraminyl-(2 leads to 3)-beta-D-galactosyl-(1 leads to 3)-N-acetyl-D-galactosaminitol. The tetrasaccharide structure from apolipoprotein C-III2 is made up of this trisaccharide plus one sialic acid residue linked to C6 of N-acetyl-D-galactosaminitol, as was shown by the assessment of chromogens formed upon alkaline degradation.
