5.3.2.6
2-hydroxymuconate tautomerase.
based on mapping to UniProt Q01468
(2Z,4E)-2-hydroxyhexa-2,4-dienedioate = (3E)-2-oxohex-3-enedioate.
-!- Involved in the meta-cleavage pathway for the degradation of phenols, modified phenols and catechols. -!- The enol form (2Z,4E)-2-hydroxyhexa-2,4-dienedioate is produced as part of this pathway and is converted to the keto form (3E)-2-oxohex- 3-enedioate by the enzyme. -!- Another keto form, (4E)-2-oxohex-4-enedioate (4-oxalocrotonate), was originally thought to be produced by the enzyme but later shown to be produced non-enzymatically.
