α-Rhamnosyl-β-glucosidase-catalyzed reactions for analysis and biotransformations of plant-based foods
(American Chemical Society, 2011-10)
Most aroma compounds exist in vegetal tissues as disaccharide conjugates, rutinose being an abundant sugar moiety in grapes. The availability of aroma precursors would facilitate analytical analysis of plant-based foods. ...
Functional and biotechnological insights into diglycosidases
(Taylor & Francis Ltd, 2011-08)
β-Glucosidases are reported to act in an exo manner and so are unable to hydrolyze the bond if another sugar is attached to a non-reducing terminus of glucose. However, endo-β-glucosidases recognizing the heterosidic linkage ...
Enzyme-mediated transglycosylation of rutinose (6-O-α-L-rhamnosyl-D-glucose) to phenolic compounds by a diglycosidase from Acremonium sp. DSM 24697
(Portland Press, 2019-01)
The structure of the carbohydrate moiety of a natural phenolic glycoside can have a significant effect on the molecular interactions and physicochemical and pharmacokinetic properties of the entire compound, which may ...
Extracellular monoenzyme deglycosylation system of 7-O-linked flavonoid β-rutinosides and its disaccharide transglycosylation activity from Stilbella fimetaria
(Springer, 2010-05)
We screened for microorganisms able to use flavonoids as a carbon source; and one isolate, nominated Stilbella fimetaria SES201, was found to possess a disaccharide-specific hydrolase. It was a cell-bound ectoenzyme that ...
Polyethyleneimine coating of magnetic particles increased the stability of an immobilized diglycosidase
(Portland Press, 2015-01)
The diglycosidase, α-rhamnosyl-β-glucosidase, from Acremonium sp. DSM24697 was immobilized by adsorption and cross-linking onto polyaniline-iron (PI) particles. The immobilization yield and the immobilization efficiency ...
Quantification of hesperidin in citrus-based foods using a fungal diglycosidase
(Elsevier, 2012-10)
A simple enzymatic-spectrophotometric method for hesperidin quantification was developed by means of a specific fungal enzyme. The method utilises the diglycosidase α-rhamnosyl-β-glucosidase (EC 3.2.1.168) to quantitatively ...
The flavonoid degrading fungus Acremonium sp. DSM 24697 produces two diglycosidases with different specificities
(Springer, 2019-12)
Diglycosidases hydrolyze the heterosidic linkage of diglycoconjugates, releasing the disaccharide and the aglycone. Usually, these enzymes do not hydrolyze or present only low activities towards monoglycosylated compounds. ...
Production of hesperetin using a covalently multipoint immobilized diglycosidase from Acremonium sp. DSM24697
(Karger, 2013-05)
The diglycosidase α-rhamnosyl-β-glucosidase (EC 3.2.1.168) from the fungus Acremonium sp. DSM24697 was immobilized on several agarose-based supports. Covalent multipoint immobilization onto glyoxyl-activated agarose was ...
