molecular function
    GO:0052595    aliphatic-amine oxidase activity    Catalysis of the reaction: an aliphatic amine + H2O + O2 = an aldehyde + NH3 + hydrogen peroxide + H+.
    GO:0052594    aminoacetone:oxygen oxidoreductase(deaminating) activity    Catalysis of the reaction: aminoacetone + H2O + O2 = methylglyoxal + NH3 + hydrogen peroxide + H+.
    GO:0005509    calcium ion binding    Interacting selectively and non-covalently with calcium ions (Ca2+).
    GO:0005507    copper ion binding    Interacting selectively and non-covalently with copper (Cu) ions.
    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:0052596    phenethylamine:oxygen oxidoreductase (deaminating) activity    Catalysis of the reaction: phenylethylamine + O2 + H2O = phenylacetaldehyde + NH3 + hydrogen peroxide + H+.
    GO:0008131    primary amine oxidase activity    Catalysis of the reaction: a primary amine + H2O + O2 = an aldehyde + NH3 + hydrogen peroxide.
    GO:0048038    quinone binding    Interacting selectively and non-covalently with a quinone, any member of a class of diketones derivable from aromatic compounds by conversion of two CH groups into CO groups with any necessary rearrangement of double bonds.
    GO:0052593    tryptamine:oxygen oxidoreductase (deaminating) activity    Catalysis of the reaction: tryptamine + H2O + O2 = NH3 + indole acetaldehyde + hydrogen peroxide + H+.
biological process
    GO:0006559    L-phenylalanine catabolic process    The chemical reactions and pathways resulting in the breakdown of phenylalanine, 2-amino-3-phenylpropanoic acid.
    GO:0009308    amine metabolic process    The chemical reactions and pathways involving any organic compound that is weakly basic in character and contains an amino or a substituted amino group. Amines are called primary, secondary, or tertiary according to whether one, two, or three carbon atoms are attached to the nitrogen atom.
    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:0019607    phenylethylamine catabolic process    The chemical reactions and pathways resulting in the breakdown of phenylethylamine, an amine with pharmacological properties similar to those of amphetamine, occurs naturally as a neurotransmitter in the brain, and is present in chocolate and oil of bitter almonds.
cellular component
    GO:0042597    periplasmic space    The region between the inner (cytoplasmic) and outer membrane (Gram-negative Bacteria) or cytoplasmic membrane and cell wall (Fungi and Gram-positive Bacteria).
