Phenolic hydroxylases
WebJun 17, 1997 · p-Hydroxybenzoate hydroxylase (EC 1.14.13.2) is a flavoprotein monooxygenase that catalyzes the incorporation of one atom of molecular oxygen into p-hydroxybenzoate to form 3,4-dihydroxybenzoate. The enzyme activates the substrate at the 3 position to electrophilic substitution by lowering the pKa of the phenolic oxygen. WebChenprakhon, P., Pimviriyakul, P., Tongsook, C., & Chaiyen, P.
