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

[edit]

As of late 2007, only one structure has been solved for this class of enzymes, with the PDB accession code 2AF7.
