[[http://www.uniprot.org/uniprot/ALKB_ECOLI ALKB_ECOLI]] Dioxygenase that repairs alkylated DNA and RNA containing 3-methylcytosine or 1-methyladenine by oxidative demethylation. Has highest activity towards 3-methylcytosine. Has lower activity towards alkylated DNA containing ethenoadenine, and no detectable activity towards 1-methylguanine or 3-methylthymine. Accepts double-stranded and single-stranded substrates. Requires molecular oxygen, alpha-ketoglutarate and iron. Provides extensive resistance to alkylating agents such as MMS and DMS (SN2 agents), but not to MMNG and MNU (SN1 agents).<ref>PMID:12226668</ref> <ref>PMID:12594517</ref> <ref>PMID:16482161</ref> <ref>PMID:19706517</ref> <ref>PMID:21068844</ref> <ref>PMID:20084272</ref>
