Beta-D-glucopyranosyl abscisate beta-glucosidase

Beta-D-glucopyranosyl abscisate beta-glucosidase (, AtBG1, ABA-beta-D-glucosidase, ABA-specific beta-glucosidase, ABA-GE hydrolase, beta-D-glucopyranosyl abscisate hydrolase) is an enzyme with systematic name beta-D-glucopyranosyl abscisate glucohydrolase. This enzyme catalyses the following chemical reaction


 * D-glucopyranosyl abscisate + H2O $$\rightleftharpoons$$ D-glucose + abscisate

The enzyme hydrolyzes the biologically inactive beta-D-glucopyranosyl ester of abscisic acid to produce active abscisate.
