Accepted name: mRNA N1-methyladenine demethylase
Reaction: N1-methyladenine in mRNA + 2-oxoglutarate + O2 = adenine in mRNA + formaldehyde + succinate + CO2
Other name(s): ALKBH3
Systematic name: mRNA-N1-methyladenine,2-oxoglutarate:oxygen oxidoreductase (formaldehyde-forming)
Comments: Contains iron(II). Catalyses oxidative demethylation of mRNA N1-methyladenine. The enzyme is also involved in alkylation repair in DNA [2].
