Oxygenase domain of the 2OGFeDO superfamily
A double-stranded beta helix (DSBH) fold domain of the 2-oxoglutarate (2OG)-Fe(II)-dependent dioxygenase (2OGFeDO) superfamily found in various eukaryotes, bacteria and bacteriophages. Members of this family catalyze nucleic acid modifications, such as thymidine hydroxylation during base J synthesis in kinetoplastids, and the conversion of 5 methyl-cytosine (5-mC) to 5-hydroxymethyl-cytosine (hmC), or further oxidation to 5-formylcytosine (5fC) and 5-carboxylcytosine (5caC). Metazoan TET proteins contain a cysteine-rich region inserted into the core of the DSBH fold. Vertebrate TET proteins are oncogenes that are mutated in various myeloid cancers. Fungal and algal versions of this family are linked to a predicted transposase and show lineage-specific expansions.
