- 3-carboxy-cis,cis-muconate cycloisomerase
In
enzymology , a 3-carboxy-cis,cis-muconate cycloisomerase (EC number|5.5.1.2) is anenzyme that catalyzes thechemical reaction :2-carboxy-2,5-dihydro-5-oxofuran-2-acetate cis,cis-butadiene-1,2,4-tricarboxylate
Hence, this enzyme has one substrate,
2-carboxy-2,5-dihydro-5-oxofuran-2-acetate , and one product,cis,cis-butadiene-1,2,4-tricarboxylate .This enzyme belongs to the family of
isomerase s, specifically intramolecularlyase s. The systematic name of this enzyme class is 2-carboxy-2,5-dihydro-5-oxofuran-2-acetate lyase (decyclizing). Other names in common use include beta-carboxymuconate lactonizing enzyme, and 3-carboxymuconolactone hydrolase. This enzyme participates inbenzoate degradation via hydroxylation .tructural studies
As of late 2007, only one structure has been solved for this class of enzymes, with the PDB accession code PDB link|1Q5N.
