Chain A,B,C,D,E,F   (PCXA_PSEPU | P00436)
molecular function
    GO:0003824    catalytic activity    Catalysis of a biochemical reaction at physiological temperatures. In biologically catalyzed reactions, the reactants are known as substrates, and the catalysts are naturally occurring macromolecular substances known as enzymes. Enzymes possess specific binding sites for substrates, and are usually composed wholly or largely of protein, but RNA that has catalytic activity (ribozyme) is often also regarded as enzymatic.
    GO:0051213    dioxygenase activity    Catalysis of an oxidation-reduction (redox) reaction in which both atoms of oxygen from one molecule of O2 are incorporated into the (reduced) product(s) of the reaction. The two atoms of oxygen may be distributed between two different products.
    GO:0008199    ferric iron binding    Interacting selectively and non-covalently with ferric iron, Fe(III).
    GO:0005506    iron ion binding    Interacting selectively and non-covalently with iron (Fe) ions.
    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.
    GO:0016702    oxidoreductase activity, acting on single donors with incorporation of molecular oxygen, incorporation of two atoms of oxygen    Catalysis of an oxidation-reduction (redox) reaction in which hydrogen or electrons are transferred from one donor, and two oxygen atoms is incorporated into a donor.
    GO:0018578    protocatechuate 3,4-dioxygenase activity    Catalysis of the reaction: 3,4-dihydroxybenzoate + O2 = 3-carboxy-cis,cis-muconate.
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:0042952    beta-ketoadipate pathway    A pathway of aromatic compound degradation by ortho-cleavage; one branch converts protocatechuate, derived from phenolic compounds, to beta-ketoadipate, and the other branch converts catechol, generated from various aromatic hydrocarbons, amino aromatics, and lignin monomers, also to beta-ketoadipate. Two additional steps accomplish the conversion of beta-ketoadipate to tricarboxylic acid cycle intermediates.
    GO:0006725    cellular aromatic compound metabolic process    The chemical reactions and pathways involving aromatic compounds, any organic compound characterized by one or more planar rings, each of which contains conjugated double bonds and delocalized pi electrons, as carried out by individual cells.
    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.
