General FunctionL-ascorbic acid binding
Specific FunctionDioxygenase that repairs alkylated DNA containing 1-methyladenine (1meA) and 3-methylcytosine (3meC) by oxidative demethylation. Has a strong preference for single-stranded DNA. Able to process alkylated 3mC within double-stranded regions via its interaction with ASCC3, which promotes DNA unwinding to generate single-stranded substrate needed for ALKHB3. May also act on RNA. Requires molecular oxygen, alpha-ketoglutarate and iron.
