Application

β-glucosidase is also used in the synthesis of glucosides and fucosides with various potential applications in pharmaceutical, cosmetic and detergent industries, hydrolytic removal of aglycone moiety from flavonoid and isoflavonoid glycosides, flavor enhancement of fruit juices and wine, and biosynthesis of oligosaccharides.

Actions biochimiques/physiologiques

βglucosidase is involved in the hydrolysis of β-glycosidic bonds connecting carbohydrate residues in β-D-glycosides. They convert cellobiose and cellooligosaccharides produced by the endo and exoglucanases to glucose.

Définition de l'unité

1 U corresponds to the amount of enzyme which liberates 1 μmol glucose per minute at pH 5.0 and 37 °C (salicin as substrate)

The transglycosylation from raffinose and lactose to Aloc-Ser-OMe is catalyzed respectively by alpha and beta galactosidases. Transglycosylation from cellobiose has been achieved with beta-glucosidase. The simplicity of the enzymatic synthesis, the stereospecificity of the condensations in one-pot reactions and the
