5-Methylcytosine (5mC) is oxidized by ten-eleven translocation (TET) enzymes. This process followed by thymine DNA glycosylase is proposed to be the mechanism for methylcytosine demethylation. 5-Hydroxymethylcytosine (5hmC) is one of the most important key oxidative metabolites in the demethylation process, and therefore, simple and accurate method to determine 5hmC at single base resolution is desired. In the present study, we developed a mild catalytic oxidation of 5-hmC using micelle incarcerated oxidants that enables to determine the position of 5hmC at single base resolution.
