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> |
