Chain A   (PHHY_PSEAE | P20586)
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.
    GO:0044550    secondary metabolite biosynthetic process    The chemical reactions and pathways resulting in the formation of secondary metabolites, the compounds that are not necessarily required for growth and maintenance of cells, and are often unique to a taxon.
