== Function ==
[https://www.uniprot.org/uniprot/ALKB2_HUMAN ALKB2_HUMAN] Dioxygenase that repairs alkylated DNA and RNA containing 1-methyladenine and 3-methylcytosine by oxidative demethylation. Can also repair alkylated DNA containing 1-ethenoadenine (in vitro). Has strong preference for double-stranded DNA. Has low efficiency with single-stranded substrates. Requires molecular oxygen, alpha-ketoglutarate and iron.<ref>PMID:12486230</ref> <ref>PMID:12594517</ref> <ref>PMID:16174769</ref> <ref>PMID:18519673</ref> <ref>PMID:18432238</ref>
