D-arabinonolactonase

In enzymology, a D-arabinonolactonase is an enzyme that catalyzes the chemical reaction


 * D-arabinono-1,4-lactone + H2O $$\rightleftharpoons$$ D-arabinonate

Thus, the two substrates of this enzyme are D-arabinono-1,4-lactone and H2O, whereas its product is D-arabinonate.

This enzyme belongs to the family of hydrolases, specifically those acting on carboxylic ester bonds. The systematic name of this enzyme class is D-arabinono-1,4-lactone lactonohydrolase.
