3-oxoadipate enol-lactonase

Class of enzymes

The enzyme 3-oxoadipate enol-lactonase (EC 3.1.1.24) catalyzes the reaction

3-oxoadipate enol-lactone + H₂O ${\displaystyle \rightleftharpoons }$ 3-oxoadipate

This enzyme belongs to the family of hydrolases, specifically those acting on carboxylic ester bonds. The systematic name is 4-carboxymethylbut-3-en-4-olide enol-lactonohydrolase. Other names in common use include carboxymethylbutenolide lactonase, β-ketoadipic enol-lactone hydrolase, 3-ketoadipate enol-lactonase, 3-oxoadipic enol-lactone hydrolase, and β-ketoadipate enol-lactone hydrolase. This enzyme participates in benzoate degradation via hydroxylation.
