Beta-apiosyl-beta-glucosidase (EC 3.2.1.161) is an enzyme that breaks a specific sugar linkage in some plant compounds called isoflavonoid glycosides. It uses water to remove a disaccharide sugar (apiosyl attached to glucosyl) from an isoflavonoid, yielding a hydroxyisoflavonoid and a glucose-containing sugar.

Substrates:
- 7-[beta-D-apiofuranosyl-(1->6)-beta-D-glucopyranosyloxy]isoflavonoid
- H2O

Products:
- 7-hydroxyisoflavonoid
- beta-D-apiofuranosyl-(1->6)-D-glucose

Enzyme family:
- Hydrolases, specifically glycosidases that break O- and S-glycosyl bonds

Systematic name:
- 7-[beta-D-apiofuranosyl-(1->6)-beta-D-glucopyranosyloxy]isoflavonoid beta-D-apiofuranosyl-(1->6)-D-glucohydrolase

Common names:
- isoflavonoid-7-O-beta[D-apiosyl-(1->6)-beta-D-glucoside] beta-glucosidase
- furcatin hydrolase
- disaccharidase
- isoflavonoid 7-O-beta-apiosyl-glucoside beta-glucosidase
