3-oxoadipate enol-lactonase

In enzymology, a 3-oxoadipate enol-lactonase (EC 3.1.1.24) is an enzyme that catalyzes the chemical reaction

3-oxoadipate enol-lactone + H₂O 3-oxoadipate

Thus, the two substrates of this enzyme are 3-oxoadipate enol-lactone and H₂O, whereas its product is 3-oxoadipate.

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