Chain A,B   (3MDO_PSEAE | Q9I0N5)
molecular function
    GO:0017172    cysteine dioxygenase activity    Catalysis of the reaction: L-cysteine + O(2) = 3-sulfino-L-alanine + H(+).
    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:0005506    iron ion binding    Interacting selectively and non-covalently with iron (Fe) 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: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.
biological process
    GO:0019451    L-cysteine catabolic process to pyruvate, using cysteine dioxygenase    The chemical reactions and pathways resulting in the breakdown into pyruvate of L-cystine, catalyzed by the enzyme cysteine dioxygenase (EC:1.13.11.20).
    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:0000097    sulfur amino acid biosynthetic process    The chemical reactions and pathways resulting in the formation of amino acids containing sulfur, comprising cysteine, methionine and selenocysteine.
    GO:0042412    taurine biosynthetic process    The chemical reactions and pathways resulting in the formation of taurine (2-aminoethanesulfonic acid), a sulphur-containing amino acid derivative important in the metabolism of fats.
cellular component
    GO:0005829    cytosol    The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
