Hence, this enzyme has one substrate, 2,4-dichloro-2,5-dihydro-5-oxofuran-2-acetate, and one product, 2,4-dichloro-cis,cis-muconate.
This enzyme belongs to the family of isomerases, specifically the class of intramolecular lyases. The systematic name of this enzyme class is 2,4-dichloro-2,5-dihydro-5-oxofuran-2-acetate lyase (decyclizing). This enzyme participates in 1,4-dichlorobenzene degradation. It employs one cofactor, manganese.
