Chain A   (ALKB_ECOLI | P05050)
molecular function
    GO:0043734    DNA-N1-methyladenine dioxygenase activity    Catalysis of the oxidative demethylation of N1-methyladenine and N3-methylcytosine in DNA, with concomitant decarboxylation of 2-oxoglutarate and releases oxidized methyl group on N1-methyladenine and N3-methylcytosine as formaldehyde.
    GO:0051747    cytosine C-5 DNA demethylase activity    Catalysis of the reaction: methyl-dCpdG DNA + H2O = dCpdG DNA + methanol. This reaction is the hydrolytic removal of the methyl group on the 5 position of cytosine in DNA.
    GO:0051213    dioxygenase activity    Catalysis of an oxidation-reduction (redox) reaction in which both atoms of oxygen from one molecule of O2 are incorporated into the (reduced) product(s) of the reaction. The two atoms of oxygen may be distributed between two different products.
    GO:0008198    ferrous iron binding    Interacting selectively and non-covalently with ferrous iron, Fe(II).
    GO:0046872    metal ion binding    Interacting selectively and non-covalently with any metal ion.
    GO:0035515    oxidative RNA demethylase activity    Catalysis of the removal of a methyl group from one or more nucleosides within a RNA molecule involving the oxidation (i.e. electron loss) of one or more atoms.
    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:0006307    DNA dealkylation involved in DNA repair    The repair of alkylation damage, e.g. the removal of the alkyl group at the O6-position of guanine by O6-alkylguanine-DNA alkyltransferase (AGT).
    GO:0080111    DNA demethylation    The removal of a methyl group from one or more nucleotides within an DNA molecule.
    GO:0006281    DNA repair    The process of restoring DNA after damage. Genomes are subject to damage by chemical and physical agents in the environment (e.g. UV and ionizing radiations, chemical mutagens, fungal and bacterial toxins, etc.) and by free radicals or alkylating agents endogenously generated in metabolism. DNA is also damaged because of errors during its replication. A variety of different DNA repair pathways have been reported that include direct reversal, base excision repair, nucleotide excision repair, photoreactivation, bypass, double-strand break repair pathway, and mismatch repair pathway.
    GO:0042245    RNA repair    Any process that results in the repair of damaged RNA.
    GO:0006974    cellular response to DNA damage stimulus    Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus indicating damage to its DNA from environmental insults or errors during metabolism.
    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.
    GO:0070989    oxidative demethylation    The process of removing one or more methyl groups from a molecule, involving the oxidation (i.e. electron loss) of one or more atoms in the substrate.
    GO:0035552    oxidative single-stranded DNA demethylation    Removal of the methyl group from one or more nucleotides within a single-stranded DNA molecule involving the oxidation (i.e. electron loss) of one or more atoms.
    GO:0035553    oxidative single-stranded RNA demethylation    Removal of the methyl group from one or more nucleotides within a single-stranded RNA molecule involving the oxidation (i.e. electron loss) of one or more atoms.
