2-pyrone-4,6-dicarboxylate lactonase.
based on mapping to UniProt O87170
2-oxo-2H-pyran-4,6-dicarboxylate + H(2)O = (1E)-4-oxobut-1-ene-1,2,4- tricarboxylate.
-!- The product is most likely the keto-form of 4-oxalmesaconate (shown). -!- It can be converted to the enol-form, 4-hydroxybuta-1,3-diene-1,2,4- trioate, either spontaneously or by EC 5.3.2.8.
