SYSTEMATIC NAME
IUBMB Comments
methyl DNA-base, 2-oxoglutarate:oxygen oxidoreductase (formaldehyde-forming)
Contains iron; activity is slightly stimulated by ascorbate. Catalyses oxidative demethylation of the DNA base lesions N1-methyladenine, N3-methylcytosine, N1-methylguanine, and N3-methylthymine. It works better on single-stranded DNA (ssDNA) and is capable of repairing damaged bases in RNA.
