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 was released to the medium during conidiogenesis. The enzyme was shown to cleave the flavonoid hesperidin (hesperetin 7-O-α-rhamnopyranosyl-β-glucopyranoside) into rutinose (α-rhamnopyranosyl-β-glucopyranose) and hesperetin. Since only intracellular traces of monoglycosidase… 
A novel Aspergillus oryzae diglycosidase that hydrolyzes 6-O-α-L-rhamnosyl-β-D-glucoside from flavonoids
Abstractα-L-Rhamnosyl-β-D-glucosidase (rutinosidase) hydrolyzes the glycosidic linkage between the disaccharide 6-O-α-L-rhamnosyl-β-D-glucoside (rutinose) and the aglycone. We identified a
Bacteria as source of diglycosidase activity: Actinoplanes missouriensis produces 6-O-α-l-rhamnosyl-β-d-glucosidase active on flavonoids
Findings demonstrate that organisms other than plants and filamentous fungi can contribute to an expansion of the diglycosidase toolbox.
α-L-Rhamnosyl-β-D-glucosidase (Rutinosidase) from Aspergillus niger: Characterization and Synthetic Potential of a Novel Diglycosidase
The utility of the recombinant rutinosidase was demonstrated by its use for the synthesis of a broad spectrum of rutinoides of primary, secondary, acyclic and phenolic alcohols as well as for the preparation of free rutinose.
The flavonoid degrading fungus Acremonium sp. DSM 24697 produces two diglycosidases with different specificities
A phylogenetic analysis showed that αRβG I grouped in glycoside hydrolase family 5, subfamily 23 (GH5), together with other fungal diglycosidases whose substrate specificities had been reported to be different from αR βG I, and thus is the first GH3 member that hydrolyzes the heterosidic linkage of rutinosylated compounds.
α-Rhamnosyl-β-glucosidase-catalyzed reactions for analysis and biotransformations of plant-based foods.
The aroma precursors were significantly hydrolyzed, which indicated the potential use of the enzyme for biotechnological applications, for example, in aroma modulation of fermented foods.
Hydrolysis of flavanone glycosides by β-glucosidase from Pyrococcus furiosus and its application to the production of flavanone aglycones from citrus extracts.
The hydrolytic activity of the recombinant β-glucosidase from Pyrococcus furiosus for the flavanone glycoside hesperidin was optimal at pH 5.5 and 95 °C and the conversion yields, concentrations, and productivities in this study are the highest among those obtained from citrus extracts.
Functional and biotechnological insights into diglycosidases*
The role of endo-β-glucosidases recognizing the heterosidic linkage in plant and filamentous fungi, as well as their prospects for technological applications are reviewed.
Enzyme‐mediated transglycosylation of rutinose (6‐O‐α‐l‐rhamnosyl‐d‐glucose) to phenolic compounds by a diglycosidase from Acremonium sp. DSM 24697
The structure of 4‐hydroxyphenyl‐β‐rutinoside was confirmed by NMR, that is, a single glycosylated product with a free hydroxyl group was formed and is a contribution to the development of convenient and sustainable processes for the glycosolation of small phenolic compounds.
Biochemical Characterization of β-Glucosidase-mediated Catabolism of Flavonol Bisglycosides in Arabidopsis thaliana
All biochemical data indicate that BGLU15 is essential for flavonol 3-O-glucoside and 3- o-glUCoside-7-o-rhamnoside catabolism in Arabidopsis, and is important for genetic engineering or traditional breeding strategies aimed at limiting Flavonol losses in commercially important horticultural and agricultural commodities.


Isolation and Characterization of a β-Primeverosidase-Like Enzyme from Penicillium multicolor
It is concluded that the present enzyme is a kind of β-diglycosidase rather than β-primeverosidase, which shows narrow substrate specificity with respect to the aglycon and glycon moieties of the diglycoside.
Furcatin Hydrolase from Viburnum furcatum Blume Is a Novel Disaccharide-specific Acuminosidase in Glycosyl Hydrolase Family 1*
Phylogenetic analysis of plant β-glucosidases revealed that FH clusters with β-primeverosidase, and this suggests that the disaccharide glycosidases will form a new subfamily in glycosyl hydrolase family 1.
Synthesis of rutinosides and rutinose by reverse hydrolysis catalyzed by fungal α-l-rhamnosidases
The synthesis of α-l-rhamnosyl(1→6)-β-d-glucosides (rutinosides) and α-l-rhamnosyl(1→6)-β-d-glucose (rutinose) catalyzed by several fungal α-l-rhamnosidases was studied by the reverse hydrolysis
