This study is the first to investigate the interactions of hemin with a G-triplex DNA of T1 using different DNA binding assays. The low intrinsic peroxidatic activity of hemin could be significantly enhanced using T1. Furthermore, much decreased oxidation enhancement by T2 or T3 with one key guanine mutation was observed, and the observed peroxidatic activity of T1 should be directly due to the G-triplex complexed with hemin.
