Template:Infobox enzyme DNA oxidative demethylase (Template:EC number, alkylated DNA repair protein, alpha-ketoglutarate-dependent dioxygenase ABH1, alkB (gene)) is an enzyme with systematic name methyl DNA-base, 2-oxoglutarate:oxygen oxidoreductase (formaldehyde-forming).[1][2][3] This enzyme catalyses the following chemical reaction
- DNA-base-CH3 + 2-oxoglutarate + O2 DNA-base + formaldehyde + succinate + CO2
DNA oxidative demethylase contains iron; activity is somewhat stimulated by ascorbate.
