Chain A   (Q8A3I2_BACTN | Q8A3I2)
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:0008757    S-adenosylmethionine-dependent methyltransferase activity    Catalysis of the transfer of a methyl group from S-adenosyl-L-methionine to a substrate.
    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:0008168    methyltransferase activity    Catalysis of the transfer of a methyl group to an acceptor molecule.
    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:0032259    methylation    The process in which a methyl group is covalently attached to a molecule.
cellular component
    GO:0005737    cytoplasm    All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
