Weakened N3 Hydrogen Bonding by 5-Formylcytosine and 5-Carboxylcytosine Reduces Their Base-Pairing Stability
In the active cytosine demethylation pathway, 5- methylcytosine (5mC) is oxidized sequentially to 5-hydroxymethylcytosine (5hmC), 5-formylcytosine (5fC), and 5-carboxylcytosine (5caC). Thymine DNA glycosylase (TDG) selectively excises 5fC and 5caC but not cytosine (C), 5mC, and 5hmC. We propose that...
