2,6-dioxo-6-phenylhexa-3-enoate hydrolase

In enzymology, a 2,6-dioxo-6-phenylhexa-3-enoate hydrolase () is an enzyme that catalyzes the chemical reaction
Thus, the two substrates of this enzyme are 2,6-dioxo-6-phenylhexa-3-enoate and H2O, whereas its two products are benzoate and 2-oxopent-4-enoate.
This enzyme belongs to the family of hydrolases, specifically those acting on carbon-carbon bonds in ketonic substances. The systematic name of this enzyme class is 2,6-dioxo-6-phenylhexa-3-enoate benzoylhydrolase. This enzyme is also called HOHPDA hydrolase. This enzyme participates in biphenyl degradation and fluorene degradation.
