The enzyme 4-carboxymuconolactone decarboxylase ( EC 4.1.1.44) catalyzes the chemical reaction
- 2-carboxy-2,5-dihydro-5-oxofuran-2-acetate 4,5-dihydro-5-oxofuran-2-acetate + CO2
This enzyme belongs to the family of lyases, specifically the carboxy-lyases, which cleave carbon-carbon bonds. The systematic name of this enzyme class is 2-carboxy-2,5-dihydro-5-oxofuran-2-acetate carboxy-lyase (4,5-dihydro-5-oxofuran-2-acetate-forming). Other names in common use include gamma-4-carboxymuconolactone decarboxylase,[ citation needed] and 4-carboxymuconolactone carboxy-lyase.[ citation needed] This enzyme participates in benzoate degradation via hydroxylation.
Structural studies
As of late 2007, only one structure has been solved for this class of enzymes, with the PDB accession code 2AF7.
