In enzymology, a 5-oxopent-3-ene-1,2,5-tricarboxylate decarboxylase (EC 4.1.1.68) is an enzyme that catalyzes the chemical reaction
- 5-oxopent-3-ene-1,2,5-tricarboxylate
2-oxohept-3-enedioate + CO2
Hence, this enzyme has one substrate, 5-oxopent-3-ene-1,2,5-tricarboxylate, and two products, 2-oxohept-3-enedioate and 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 5-oxopent-3-ene-1,2,5-tricarboxylate carboxy-lyase (2-oxohept-3-enedioate-forming). Other names in common use include 5-carboxymethyl-2-oxo-hex-3-ene-1,6-dioate decarboxylase, and 5-oxopent-3-ene-1,2,5-tricarboxylate carboxy-lyase. This enzyme participates in tyrosine metabolism.
Structural studies
As of late 2007, only one structure has been solved for this class of enzymes, with the PDB accession code 1I7O.
