Fluorescence resonance energy transfer (FRET) has been used to study the global folding of an uranyl (UO 2 2 + )-specific 39E DNAzyme in the presence of Mg 2 + , Zn 2 + , Pb 2 + , or UO 2 2 + . At pH 5.5 and physiological ionic strength (100 mm Na + ), two of the three stems in this DNAzyme folded i
