Asymmetric/Biological Unit(hide GO term definitions)
Chain A   (T1SK_ECOLI | P05719)
molecular function
    GO:0003677    DNA binding    Any molecular function by which a gene product interacts selectively and non-covalently with DNA (deoxyribonucleic acid).
biological process
    GO:0006304    DNA modification    The covalent alteration of one or more nucleotide sites in DNA, resulting in a change in its properties.
    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.

Chain B,C   (T1MK_ECOLI | P08957)
molecular function
    GO:0003677    DNA binding    Any molecular function by which a gene product interacts selectively and non-covalently with DNA (deoxyribonucleic acid).
    GO:0008170    N-methyltransferase activity    Catalysis of the transfer of a methyl group to the nitrogen atom of an acceptor molecule.
    GO:0008168    methyltransferase activity    Catalysis of the transfer of a methyl group to an acceptor molecule.
    GO:0003676    nucleic acid binding    Interacting selectively and non-covalently with any nucleic acid.
    GO:0009007    site-specific DNA-methyltransferase (adenine-specific) activity    Catalysis of the reaction: S-adenosyl-L-methionine + DNA adenine = S-adenosyl-L-homocysteine + DNA 6-methylaminopurine.
    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:0006306    DNA methylation    The covalent transfer of a methyl group to either N-6 of adenine or C-5 or N-4 of cytosine.
    GO:0032775    DNA methylation on adenine    The covalent transfer of a methyl group to N-6 of adenine 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.
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.

Chain D,E   (OCR_BPT7 | P03775)
biological process
    GO:0016032    viral process    A multi-organism process in which a virus is a participant. The other participant is the host. Includes infection of a host cell, replication of the viral genome, and assembly of progeny virus particles. In some cases the viral genetic material may integrate into the host genome and only subsequently, under particular circumstances, 'complete' its life cycle.
