Deoxylimonate A ring lactonase

In enzymology, a deoxylimonate A-ring-lactonase (EC 3.1.1.46) is an enzyme that catalyzes the chemical reaction

Thus, the two substrates of this enzyme are deoxylimonate and H₂O, whereas its product is deoxylimononic acid D-ring-lactone.

This enzyme belongs to the family of hydrolases, specifically those acting on carboxylic ester bonds. The systematic name of this enzyme class is deoxylimonate A-ring-lactonohydrolase.
