Beta-apiosyl-beta-glucosidase

In enzymology, a beta-apiosyl-beta-glucosidase (EC number|3.2.1.161) is an enzyme that catalyzes the chemical reaction

:7- [beta-D-apiofuranosyl-(1->6)-beta-D-glucopyranosyloxy] isoflavonoid + H₂O $ightleftharpoons$ a 7-hydroxyisoflavonoid + beta-D-apiofuranosyl-(1->6)-D-glucose

The 3 substrates of this enzyme are [7- [beta-D-apiofuranosyl-(1->6)-beta-D-] , glucopyranosyloxy] isoflavonoid, and H₂O, whereas its two products are 7-hydroxyisoflavonoid and beta-D-apiofuranosyl-(1->6)-D-glucose.

This enzyme belongs to the family of hydrolases, specifically those glycosidases that hydrolyse O- and S-glycosyl compounds. The systematic name of this enzyme class is 7- [beta-D-apiofuranosyl-(1->6)-beta-D-glucopyranosyloxy] isoflavonoid beta-D-apiofuranosyl-(1->6)-D-glucohydrolase. Other names in common use include isoflavonoid-7-O-beta [D-apiosyl-(1->6)-beta-D-glucoside] , disaccharidase, isoflavonoid 7-O-beta-apiosyl-glucoside beta-glucosidase, and furcatin hydrolase.
