Thus, the two substrates of this enzyme are (R)-prunasin and H2O, whereas its two products are D-glucose and mandelonitrile.
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 prunasin beta-D-glucohydrolase. This enzyme is also called prunasin hydrolase.
