ID 5.3.2.8 DE 4-oxalomesaconate tautomerase. CA (1E)-4-oxobut-1-ene-1,2,4-tricarboxylate = 4-carboxy-2-hydroxy-cis,cis- CA muconate. CC -!- This enzyme has been characterized from the bacterium Pseudomonas CC putida KT2440 and is involved in the degradation pathway of syringate CC and gallate. CC -!- It catalyzes the interconversion of two of the tautomers of CC 4-oxalomesaconate, a reaction that can also occur spontaneously. CC -!- Formerly EC 5.3.3.16. DR Q88JY0, GALD_PSEPK ; //
