Abnormal DNA methylation patterns caused by altered DNA methyltransferase (MTase) activity are closely associated with cancer. Herein, using DNA adenine methylation methyltransferase (Dam MTase) as a model analyte, we designed an allosteric molecular beacon (aMB) for sensitive detection of Dam MTase activity.

Specific and sensitive detection of DNA MTase activity can be achieved by a single-ribonucleotide repair-mediated ligation-dependent cycling signal amplification approach.
