Fluorescence emission spectra resulting from treatment of 16-nt hairpin DNA-Cf15 with Fe(II)·BLM A5 in the presence or absence of 64-nt hairpin DNAs. The reaction mixture contained 0.72 μM Fe(II)·BLM A5, 0.72 μM hairpin DNA-Cf15, and 0.72 μM hairpin DNA 2, 7, 12, or 13 in 10 mM Na cacodylate buffer solution, pH 7.0, containing 100 mM NaCl. The fluorescence emission spectra were obtained following excitation at 310 nm and 25 °C. Also shown is the fluoresence emission spectrum of the 16-nt hairpin DNA-Cf15 treated with BLM A5 in the absence of any 64-nt hairpin DNA under the same conditions (“no competitor”).
