Entry
EC 5.3.2.8                  Enzyme                                 

Name
4-oxalomesaconate tautomerase;
GalD
Class
Isomerases;
Intramolecular oxidoreductases;
Interconverting keto- and enol-groups
BRITE hierarchy
Sysname
4-oxalomesaconate keto---enol-isomerase
Reaction(IUBMB)
(1E)-4-oxobut-1-ene-1,2,4-tricarboxylate = (1E,3E)-4-hydroxybuta-1,3-diene-1,2,4-tricarboxylate [RN:R07839]
Reaction(KEGG)
Substrate
(1E)-4-oxobut-1-ene-1,2,4-tricarboxylate [CPD:C04434]
Product
(1E,3E)-4-hydroxybuta-1,3-diene-1,2,4-tricarboxylate [CPD:C04324]
Comment
This enzyme has been characterized from the bacterium Pseudomonas putida KT2440 and is involved in the degradation pathway of syringate and 3,4,5-trihydroxybenzoate. It catalyses the interconversion of two of the tautomers of 4-oxalomesaconate, a reaction that can also occur spontaneously.
