General annotation (Comments)

Function	Glycosidase probably involved in the intestinal absorption and metabolism of dietary flavonoid glycosides. Able to hydrolyze a broad variety of glycosides including phytoestrogens, flavonols, flavones, flavanones and cyanogens By similarity.
Catalytic activity	Hydrolysis of terminal, non-reducing beta-D-glucosyl residues with release of beta-D-glucose.
Subcellular location	Cytoplasm › cytosol By similarity.
Post-translational modification	The N-terminus is blocked By similarity.
Sequence similarities	Belongs to the glycosyl hydrolase 1 family. Klotho subfamily.
