Reaction
Wide substrate specificity, active on aryl-beta-D-galactose, -alpha-L-fucose, -beta-D-glucose and -beta-D-xylose and on di- and oligosaccharides. D-Glucose dimers are hydrolysed in the order of decreasing efficiency: beta-(1,3), beta-(1,4), beta-(1,6). Exo-acting enzyme with a preference for cellotetraose. =

food industry
nutrition
-
catalyst of lactose hydrolysis in dairy products in the food industry
synthesis
-
the enzyme suitable for hydrolysis of lactose at temperatures at 70-80°C
food industry
-
the immobilized enzyme is useful for the hydrolysis of lactose in whey or milk by using a packed-bed enzyme reactor operated at 70°C
-
a continuous stirred-tank reactor charged with the enzyme and operated at steady-state conditions could be a useful reaction system for the production of galacto-oligosaccharides in which composition is narrower and more easily programmable, in terms of the individual components contained, as compared to the batchwise reaction
synthesis
-
development of a continuous cellobiose hydrolysis system for glucose production with a high degree of conversion by the enzyme immobilized on chitosan activated with glutaraldehyde
synthesis
-
enzymatic synthesis of 2-beta-D-galactopyranosyloxyethyl methacrylate starting from 2-hydroxyethyl methacrylate and 4-nitrophenyl-beta-D-galactopyranoside
synthesis
-
enzymatic synthesis of polyol- and masked polyol-glycosides. The enzyme performs the synthesis of glycosides in a competitive high yield compared with that obtained with mesophilic enzymes. It permits the use of a wide variety of acceptors including tetritol compounds and their masked or protected derivatives. The synthesis of glucosides of 2,3-isopropylidene protected pure enantiomers of threitol shows the possibility of obtaining reasonable yields of products in the presence of a scarce amount of the acceptor by adding aliquots of donor at time intervals, in such a way that a molar excess of acceptor was maintained, thus avoiding undesirable formation of glycosides of the donor or enzymatic hydrolysis of the product
synthesis
formation of mannosides and xylosides by transglycosylation
synthesis
-
high yield production of hydroxytyrosol from a commercially available oleuropein by using the immobilised recombinant EcSbgly from the hyperthermophilic archaeon Sulfolobus solfataricus on chitosan support
synthesis
-
industrial production of galactooligosaccharides, very efficient enzyme for the synthesis of beta-galactooligosaccharides because of its high product yields, transfer rates, substrate specificity, and thermostability
synthesis
optimization of hexyl-beta-D-glycoside synthesis from lactose in hexanol at low water activity and high temperature. Compared to other beta-glycosidases in lactose conversion into alkyl glycoside, the enzyme shows high activity in a hexanol one-phase system and synthesized high yields of both hexyl-beta-D-galactoside and hexyl-beta-D-glucoside. Using 32 g/l lactose (93 mM), the enzyme synthesizes yields of 41% galactoside (38.1 mM) and 29% glucoside (27.0 mM)
synthesis
-
synthesis of 2-deoxyglycosides and 2-deoxygalactosides from glucal or galactal as donors. The yields observed with alkyl acceptors confirms that the robustness of the biocatalyst is of great help in designing practical syntheses of pure beta-anomers of 2-deoxy derivatives of 4-penten-1-ol (obtained in 80% yield at 20 fold molar excess) and 3,4-dimethoxybenzyl alcohol (obtained in 19% yield at 3.3 fold molar excess). The attachment of 2-deoxyglyco units is performed on various pyranosidic acceptors (4-nitrophenyl alpha-D-glucopyranoside, 2-nitrophenyl 2-deoxy-N-acetyl-alpha-D-glucosamine and 4-nitrophenyl 2-deoxy-N-acetyl-beta-D-glucosamine). At low molecular excesses of the acceptors, satisfactory yields (20-40%) of chromophoric 2-deoxy di- and trisaccharides are obtained

-
synthesis of ginsenoside K (20-O-beta-D-glucopyranosyl-20(S)-protopanaxadiol) by a recombinant enzyme. 20-O-beta-D-Glucopyranosyl-20(S)-protopanaxadiol has anti-tumor, anti-inflammatory, anti-allergic and hepatoprotective effects

synthesis
application of the alpha-L-arabinofuranosidase from Caldicellulosiruptor saccharolyticus along with the beta-glycosidase from Sulfolobus solfataricus to yield ginsenoside compound K from the protopanaxadiol-type ginsenosides in red-ginseng extracts. The optimal reaction conditions are pH 6.0, 80°C, 2 U/ml beta-glucosidase, 3 U/ml alpha-L-arabinofuranosidase, and 7.5 g/l ginsenosides in red-ginseng extract. Under these optimized conditions 4.2 g/l ginsenoside compound K from 7.5 g/l protopanaxadiol-type ginsenosides is obtained in 12 h without other ginsenosides, with a molar yield of 100% and a productivity of 348 mg/l/h
