p-hydroxybenzoate hydroxylase

UniProtKB accession:  P00438

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Catalyzes the incorporation of an atom of dioxygen into p-hydroxybenzoate (p-OHB) to form 3,4-dihydroxybenzoate (3,4DOHB). The reaction occurs in two parts: reduction of the flavin adenine dinucleotide (FAD) in the enzyme by reduced nicotinamide adenine dinucleotide phosphate (NADPH) in response to binding p-hydroxybenzoate to the enzyme and oxidation of reduced FAD with oxygen to form a hydroperoxide, which then oxygenates p-hydroxybenzoate.
