    → Modified Residue (blue background, lower-case, 'x' indicates undefined single-letter code, labelled with number + name)
  x → Chemical Group (purple background, 'x', labelled with number + name, e.g. ACE or NH2)
  extra numbering lines below/above indicate numbering irregularities and modified residue names etc., number ends below/above '|'

Chain A,B   (PER1_ARAHY | P22195)
molecular function
    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.
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: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.
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.
