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 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.
