Chain A,D   (DSVA_DESVH | P45574)
molecular function
    GO:0051539    4 iron, 4 sulfur cluster binding    Interacting selectively and non-covalently with a 4 iron, 4 sulfur (4Fe-4S) cluster; this cluster consists of four iron atoms, with the inorganic sulfur atoms found between the irons and acting as bridging ligands.
    GO:0020037    heme binding    Interacting selectively and non-covalently with heme, any compound of iron complexed in a porphyrin (tetrapyrrole) ring.
    GO:0018551    hydrogensulfite reductase activity    Catalysis of the reaction: trithionate + acceptor + 2 H2O + OH- = 3 HSO3- + reduced acceptor.
    GO:0051536    iron-sulfur cluster binding    Interacting selectively and non-covalently with an iron-sulfur cluster, a combination of iron and sulfur atoms.
    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.
biological process
    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.

Chain B,E   (DSVB_DESVH | P45575)
molecular function
    GO:0051539    4 iron, 4 sulfur cluster binding    Interacting selectively and non-covalently with a 4 iron, 4 sulfur (4Fe-4S) cluster; this cluster consists of four iron atoms, with the inorganic sulfur atoms found between the irons and acting as bridging ligands.
    GO:0009055    electron carrier activity    Any molecular entity that serves as an electron acceptor and electron donor in an electron transport chain. An electron transport chain is a process in which a series of electron carriers operate together to transfer electrons from donors to any of several different terminal electron acceptors to generate a transmembrane electrochemical gradient.
    GO:0020037    heme binding    Interacting selectively and non-covalently with heme, any compound of iron complexed in a porphyrin (tetrapyrrole) ring.
    GO:0018551    hydrogensulfite reductase activity    Catalysis of the reaction: trithionate + acceptor + 2 H2O + OH- = 3 HSO3- + reduced acceptor.

    GO:0006790    sulfur compound metabolic process    The chemical reactions and pathways involving the nonmetallic element sulfur or compounds that contain sulfur, such as the amino acids methionine and cysteine or the tripeptide glutathione.

Chain C,F   (DSVC_DESVH | P45573)
