Thus, the two substrates of this enzyme are beta-L-arabinoside and H2O, whereas its two products are L-arabinose and alcohol.
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 beta-L-arabinoside arabinohydrolase. This enzyme is also called vicianosidase.
