BRITE hierarchy
Sysname
mRNA-N1-methyladenine,2-oxoglutarate:oxygen oxidoreductase (formaldehyde-forming)
Reaction(IUBMB)
N1-methyladenine in mRNA + 2-oxoglutarate + O2 = adenine in mRNA + formaldehyde + succinate + CO2
Substrate
N1-methyladenine in mRNA;
2-oxoglutarate [CPD:
C00026 ];
O2 [CPD:
C00007 ]
Product
Comment
Contains iron(II). Catalyses oxidative demethylation of mRNA N1-methyladenine. The enzyme is also involved in alkylation repair in DNA [2].
