SYSTEMATIC NAME
IUBMB Comments
4-oxalomesaconate keto-enol-isomerase
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.
