In enzymology, a beta-apiosyl-beta-glucosidase is an enzyme that catalyzes the chemical reaction 7-[beta-D-apiofuranosyl--beta-D-glucopyranosyloxy]isoflavonoid + H2O ⇌ {\displaystyle \rightleftharpoons } a 7-hydroxyisoflavonoid + beta-D-apiofuranosyl--D-glucoseThe 3 substrates of this enzyme are [[7-[beta-D-apiofuranosyl--beta-D-]], [[glucopyranosyloxy]isoflavonoid]], and H2O, whereas its two products are 7-hydroxyisoflavonoid and [[beta-D-apiofuranosyl--D-glucose]].
