ß-Diglycosidases from microorganisms as industrial biocatalysts: biochemical characteristics and potential applications.

ABSTRACT

Flavonoid glycoside degradation can proceed through two alternative enzymatic pathways one that is mediated by monoglycosidases, and the other catalyzed by a diglycosidase. ß-Diglycosidase performs the flavonoid deglycosylation in a single reaction. The characterized ß-diglycosidase activities recognize the following disaccharidic sugar moieties ß-primeverose, acuminose, vicianose, and ß-rutinose. The present paper reviews the biochemical characteristics and potential industrial applications of microbial ß-diglycosidases that break down plant diglycoconjugated flavonoids.
