Efficient Biotransformation of Icariin to Baohuoside I Using Two Novel GH1 β-Glucosidases.

ABSTRACT: Epimedium Folium (EF) is a traditional Chinese herbal medicine, and its primary bioactive ingredients, such as icariin, are flavonoid glycosides. A rare EF flavonoid, baohuoside I, exhibits superior bioactivities and enhanced bioavailability compared to its metabolic precursor icariin. The biotransformation of icariin to baohuoside I can be effectively and specifically achieved by β-glucosidases. In this study, 33 candidate full-length β-glucosidase genes were screened from a previously built carbohydrate active enzyme (CAZyme) gene dataset derived from cow fecal microbiota. Thirteen of them exhibited β-glucosidase activity, with DCF-bgl-26 and DCF-bgl-27 showing relatively high expression levels and β-glucosidase activity. The maximum β-glucosidase activity of DCF-bgl-26 and DCF-bg
