ID 4.1.1.77 DE 4-oxalocrotonate decarboxylase. AN 4-oxalocrotonate carboxy-lyase. CA (2Z)-5-oxohex-2-enedioate = 2-oxopent-4-enoate + CO(2). CC -!- Involved in the meta-cleavage pathway for the degradation of phenols, CC modified phenols and catechols. CC -!- The enzyme has been reported to accept the tautomeric forms (2Z)-5- CC oxohex-2-enedioate and (3Z)-2-oxohex-3-enedioate as well as CC 4-oxalocrotonate and (3E)-2-oxohex-3-enedioate.
