Amygdalin beta-glucosidase

The enzyme amygdalin β-glucosidase (Template:EnzExplorer) catalyzes the following chemical reaction:

(R)-amygdalin + H₂O $\rightleftharpoons$ (R)-prunasin + D-glucose

Thus, the two substrates of this enzyme are (R)-amygdalin and H₂O, whereas its two products are (R)-prunasin and 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 amygdalin beta-D-glucohydrolase. Other names in common use include amygdalase, amygdalinase, amygdalin hydrolase, and amygdalin glucosidase.

It can be completely inhibited by the action of Glucono-δ-lactone at 1 mM concentration.
