2,6-dioxo-6-phenylhexa-3-enoate + H2O = benzoate + 2-oxopent-4-enoate catalytic mechanism involving enol-to-keto tautomerization that consists of two elementary reactions, the calculated Boltzmann weighted average barriers favor a substrate-assisted acylation mechanism, and the most feasible acylation pathway involves a catalytic triad, Ser-His-Asp. The product (2-hydroxypenta-2,4-dienoic acid) of the acylation process is replaced by three water molecules, and one of which is involved in the deacylation process, quantum mechanics/molecular mechanics study, overview Paraburkholderia xenovorans
