Carboxy-cis,cis-muconate cyclase


Carboxy-cis,cis-muconate cyclase

In enzymology, a carboxy-cis,cis-muconate cyclase (EC number|5.5.1.5) is an enzyme that catalyzes the chemical reaction

:3-carboxy-2,5-dihydro-5-oxofuran-2-acetate ightleftharpoons 3-carboxy-cis,cis-muconate

Hence, this enzyme has one substrate, 3-carboxy-2,5-dihydro-5-oxofuran-2-acetate, and one product, 3-carboxy-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 3-carboxy-2,5-dihydro-5-oxofuran-2-acetate lyase (decyclizing). This enzyme is also called 3-carboxymuconate cyclase. This enzyme participates in benzoate degradation via hydroxylation.

tructural studies
