Asymmetric Unit(hide GO term definitions)
Chain A   (PRXC_CURIN | P49053)
molecular function
    GO:0016691    chloride peroxidase activity    Catalysis of the reaction: 2 R-H + 2 chloride + hydrogen peroxide = 2 R-Cl + 2 H2O.
    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.
biological process
    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: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.
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.
