The enzyme deoxylimonate A-ring-lactonase (EC 3.1.1.46) catalyzes the reaction
- deoxylimonate + H2O [math]\displaystyle{ \rightleftharpoons }[/math] deoxylimononic acid D-ring-lactone
The reaction opens the A-ring-lactone of the triterpenoid deoxylimonic acid, leaving the D-ring-lactone intact.
This enzyme belongs to the family of hydrolases, specifically those acting on carboxylic ester bonds. The systematic name is deoxylimonate A-ring-lactonohydrolase.
