We found that Escherichia coli MazF toxin, an ACA-sequence-specific endoribonuclease, was sensitive to N-6-methyladenosine (m6A), representing the first m6A-sensitive RNA cleavage enzyme. The methyl-sensitivity of MazF allowed simple analyses of both m6A demethylase and methyltransferase activity. Furthermore, the approach could be used for inhibitor screening.
