Asymmetric/Biological Unit(hide GO term definitions)
Chain A   (PERL_BUBBU | A5JUY8)
molecular function
    GO:0005509    calcium ion binding    Interacting selectively and non-covalently with calcium ions (Ca2+).
    GO:0020037    heme binding    Interacting selectively and non-covalently with heme, any compound of iron complexed in a porphyrin (tetrapyrrole) ring.
    GO:0046872    metal ion binding    Interacting selectively and non-covalently with any metal ion.
    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:0004601    peroxidase activity    Catalysis of the reaction: donor + hydrogen peroxide = oxidized donor + 2 H2O.
    GO:0036393    thiocyanate peroxidase activity    Catalysis of the reaction: thiocyanate (SCN-) + hydrogen peroxide (H2O2) = hypothiocyanite (OSCN-) + 2 H2O. Catalyzes the hydrogen peroxide oxidation of thiocyanate.
biological process
    GO:0019731    antibacterial humoral response    An immune response against bacteria mediated through a body fluid. Examples of this process are the antibacterial humoral responses in Mus musculus and Drosophila melanogaster.
    GO:0098869    cellular oxidant detoxification    Any process carried out at the cellular level that reduces or removes the toxicity superoxide radicals or hydrogen peroxide.
    GO:0042742    defense response to bacterium    Reactions triggered in response to the presence of a bacterium that act to protect the cell or organism.
    GO:0042744    hydrogen peroxide catabolic process    The chemical reactions and pathways resulting in the breakdown of hydrogen peroxide (H2O2).
    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:0006979    response to oxidative stress    Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of oxidative stress, a state often resulting from exposure to high levels of reactive oxygen species, e.g. superoxide anions, hydrogen peroxide (H2O2), and hydroxyl radicals.
    GO:0018969    thiocyanate metabolic process    The chemical reactions and pathways involving thiocyanate, the anion of thiocyanic acid, a toxic cyanide derivative commonly formed as a by-product in the production of gas for fuel, coke, and substances for chemical industries.
cellular component
    GO:0005576    extracellular region    The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite.
    GO:0005615    extracellular space    That part of a multicellular organism outside the cells proper, usually taken to be outside the plasma membranes, and occupied by fluid.
