The reversal of the hydrolytic activity of α-mannosidase from jack bean has been studied in high concentrations of mannose. From an initial concentration of 85% mannose (w/w), a maximum yield of 70% (w/w) di- and oligosaccharides was obtained. The p

Trifluoroacetolysis of d -glucuronic acid and methyl α- d -glucopyranosiduronic acid resulted in an initial phase of degradation followed by stabilisation of the compounds as their 6,3-lactones. The methyl ester of methyl 4-O-methyl-α- d -glucopyra

Three naturally occurring isomers of the disaccharideO-α-d-mannosyl-d-mannoside were synthesized by reversing the hydrolytic activity of jack bean α-mannosidase at 75°C in a very high concentration of mannose. Higher oligosaccharides were also obt

beta-D-Galp-(1----3)-D-GalNAc (1) was synthesised from lactose and GalNAc on a mmolar scale by transgalactosylation using beta-D-galactosidase from bovine testes. The large proportions of unwanted oligosaccharides in the product mixture were removed

O-Methylation of simple neutral oligosaccharides is readily accomplished in dimethyl sulphoxide containing solid sodium hydroxide and methyl iodide [Cincanu I, Kerek F (1984) Carbohydr Res 131∶209-17]. This procedure has been extended to 2-acetamid

Oligosaccharides from the linkage-region tetrasaccharide, beta-D-GlcpA-(1----3)-beta-D-Galp-(1----3)-beta-D-Galp-(1----4)-D- Xylp, of chondroitin 4-sulphate were isolated after trifluoroacetolysis. The oligosaccharides were purified by ion-exchange c

A number of glycosphingolipids have been subjected to trifluoroacetolysis. Heating the glycosphingolipid at 100 degrees C for 48 h in mixtures of trifluoroacetic acid (TFA) and trifluoroacetic anhydride (TFAA) varying from 1:1 to 1:100 (v/v) resulted

Peptide fragments were generated by enzymic or chemical degradation of the small form, G2, and the large form, G1, of Aspergillus niger glucoamylase (EC 3.1.2.3). The G2 form was either identical to residues Ala1– Pro512 or to Ala1– Ala514 of the

Glucoamylase G1 from Aspergillus niger contains an unusual type of carbohydrate-protein linkage, involving mannose O-glycosidically linked to serine and threonine. The majority of the neutral oligosaccharides of glucoamylase G1 are located in a regio
