Dienelactone hydrolase (DLHase) catalyses the hydrolysis of dienelactone to maleylacetate. This reaction is part of the beta-ketoadipate pathway used in bacteria and fungi to degrade aromatic compounds. Bacteria which utilise this pathway play an important role in the detoxification of many toxic halogenated aromatic compounds produced in industry. DLHase is a member of the alpha/beta hydrolase superfamily, although it does not possess a Ser-Hys-Asp catalytic triad and instead uses a triad of Cys-His-Asp.
