Chain A   (PHHY_PSEFL | P00438)
molecular function
    GO:0018659    4-hydroxybenzoate 3-monooxygenase activity    Catalysis of the reaction: 4-hydroxybenzoate + NADPH + H+ + O2 = protocatechuate + NADP+ + H2O.
    GO:0071949    FAD binding    Interacting selectively and non-covalently with the oxidized form, FAD, of flavin-adenine dinucleotide, the coenzyme or the prosthetic group of various flavoprotein oxidoreductase enzymes.
    GO:0050660    flavin adenine dinucleotide binding    Interacting selectively and non-covalently with FAD, flavin-adenine dinucleotide, the coenzyme or the prosthetic group of various flavoprotein oxidoreductase enzymes, in either the oxidized form, FAD, or the reduced form, FADH2.
    GO:0004497    monooxygenase activity    Catalysis of the incorporation of one atom from molecular oxygen into a compound and the reduction of the other atom of oxygen to water.
    GO:0016491    oxidoreductase activity    Catalysis of an oxidation-reduction (redox) reaction, a reversible chemical reaction in which the oxidation state of an atom or atoms within a molecule is altered. One substrate acts as a hydrogen or electron donor and becomes oxidized, while the other acts as hydrogen or electron acceptor and becomes reduced.
biological process
    GO:0019439    aromatic compound catabolic process    The chemical reactions and pathways resulting in the breakdown of aromatic compounds, any substance containing an aromatic carbon ring.
    GO:0043639    benzoate catabolic process    The chemical reactions and pathways resulting in the breakdown of benzoate, the anion of benzoic acid (benzenecarboxylic acid), a fungistatic compound widely used as a food preservative; it is conjugated to glycine in the liver and excreted as hippuric acid.
    GO:0043640    benzoate catabolic process via hydroxylation    The chemical reactions and pathways resulting in the breakdown of benzoate, by its hydroxylation to cis-1,2-dihydroxybenzoate followed by dehydrogenation to catechol.
    GO:0055114    oxidation-reduction process    A metabolic process that results in the removal or addition of one or more electrons to or from a substance, with or without the concomitant removal or addition of a proton or protons.
