1.14.11.54

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].
