mRNA-N1-methyladenine,2-oxoglutarate:oxygen oxidoreductase (formaldehyde-forming)

N1-methyladenine in mRNA + 2-oxoglutarate + O2 = adenine in mRNA + formaldehyde + succinate + CO2

N1-methyladenine in mRNA;
2-oxoglutarate [CPD:C00026];
O2 [CPD:C00007]

Contains iron(II). Catalyses oxidative demethylation of mRNA N1-methyladenine. The enzyme is also involved in alkylation repair in DNA [2].
