EC 3.7.1.8

Accepted name: 2,6-dioxo-6-phenylhexa-3-enoate hydrolase

Reaction: 2,6-dioxo-6-phenylhexa-3-enoate + H2O = benzoate + 2-oxopent-4-enoate

Other name(s): HOHPDA hydrolase

Systematic name: 2,6-dioxo-6-phenylhexa-3-enoate benzoylhydrolase

Comments: Cleaves the products from biphenol, 3-isopropylcatechol and 3-methylcatechol produced by EC 1.13.11.39 biphenyl-2,3-diol 1,2-dioxygenase, by ring-fission at a -CO-C bond. Involved in the breakdown of biphenyl-related compounds by Pseudomonas sp.
