Abstract

The Tet family of dioxygenase enzymes convert 5-methylcytosine to 5-hydroxymethylcytosine, 5-formylcytosine and 5-carboxylcytosine, which has an effect on gene expression; here the structure of NgTet1, a Tet-like protein with the same activity as mammalian Tet1, is determined, showing that NgTet1 uses a base-flipping mechanism to access 5-methylcytosine.
