Chain A   (SUFU_BACSU | O32163)
molecular function
    GO:0051537    2 iron, 2 sulfur cluster binding    Interacting selectively and non-covalently with a 2 iron, 2 sulfur (2Fe-2S) cluster; this cluster consists of two iron atoms, with two inorganic sulfur atoms found between the irons and acting as bridging ligands.
    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:0008198    ferrous iron binding    Interacting selectively and non-covalently with ferrous iron, Fe(II).
    GO:0005506    iron ion binding    Interacting selectively and non-covalently with iron (Fe) ions.
    GO:0051536    iron-sulfur cluster binding    Interacting selectively and non-covalently with an iron-sulfur cluster, a combination of iron and sulfur atoms.
    GO:0036455    iron-sulfur transferase activity    Catalysis of the transfer of a iron-sulfur cluster from one compound (donor) to another (acceptor).
    GO:0046872    metal ion binding    Interacting selectively and non-covalently with any metal ion.
    GO:0005515    protein binding    Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
    GO:0016740    transferase activity    Catalysis of the transfer of a group, e.g. a methyl group, glycosyl group, acyl group, phosphorus-containing, or other groups, from one compound (generally regarded as the donor) to another compound (generally regarded as the acceptor). Transferase is the systematic name for any enzyme of EC class 2.
biological process
    GO:0044571    [2Fe-2S] cluster assembly    The incorporation of two iron atoms and two sulfur atoms into an iron-sulfur cluster.
    GO:0006879    cellular iron ion homeostasis    Any process involved in the maintenance of an internal steady state of iron ions at the level of a cell.
    GO:0016226    iron-sulfur cluster assembly    The incorporation of iron and exogenous sulfur into a metallo-sulfur cluster.
    GO:0097428    protein maturation by iron-sulfur cluster transfer    The transfer of an assembled iron-sulfur cluster from a scaffold protein to an acceptor protein that contributes to the attainment of the full functional capacity of a protein.
cellular component
    GO:0005737    cytoplasm    All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
