In enzymology, a glutaconyl-CoA decarboxylase (EC 7.2.4.5) is an enzyme that catalyzes the chemical reaction [1]
- (2E)-glutaconyl-CoA + H+ + Na+(in) (2E)-butenoyl-CoA + CO
2 + Na+(out)
Hence, this enzyme has one substrate, (2E)-glutaconyl-CoA, and two products, (2E)-butenoyl-CoA and CO2. During the process, a sodium ion is transported across the membrane. Previously, this enzyme was classified as EC 4.1.1.70. [1] [2]
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 4-carboxybut-2-enoyl-CoA carboxy-lyase (but-2-enoyl-CoA-forming). Other names in common use include glutaconyl coenzyme A decarboxylase, pent-2-enoyl-CoA carboxy-lyase, and 4-carboxybut-2-enoyl-CoA carboxy-lyase. This enzyme participates in benzoate degradation via coa ligation and butanoate metabolism.
As a decarboxylase, the enzyme requires biotin for its function. [1] [2]
