Uronolactonase

The enzyme uronolactonase (EC 3.1.1.19) catalyzes the reaction


 * D -glucurono-6,2-lactone + H2O $$\rightleftharpoons$$ D -glucuronate

This enzyme belongs to the family of hydrolases, specifically those acting on carboxylic ester bonds. The systematic name is  D -glucurono-6,2-lactone lactonohydrolase. It is also called glucuronolactonase. It participates in ascorbate and aldarate metabolism.
