Asymmetric/Biological Unit(hide GO term definitions)
Chain A   (Q8X8S5_ECO57 | Q8X8S5)
molecular function
    GO:0003886    DNA (cytosine-5-)-methyltransferase activity    Catalysis of the reaction: S-adenosyl-L-methionine + DNA containing cytosine = S-adenosyl-L-homocysteine + DNA containing 5-methylcytosine.
    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:0090116    C-5 methylation of cytosine    The covalent transfer of a methyl group to C-5 of cytosine in a DNA molecule.
    GO:0009307    DNA restriction-modification system    A defense process found in many bacteria and archaea that protects the organism from invading foreign DNA by cleaving it with a restriction endonuclease. The organism's own DNA is protected by methylation of a specific nucleotide, which occurs immediately following replication, in the same target site as the restriction enzyme.
    GO:0032259    methylation    The process in which a methyl group is covalently attached to a molecule.
