Identification by MALDI mass spectrometry of DNA-catalyzed DNA cleavage products formed by the RadDz3 deoxyribozyme. This spectrum is of the crude RadDz3 products formed in the absence of H2O2 (see the Experimental Section for preparative details). Essentially the same mass spectrum was observed for a sample prepared in the presence of 100 µM H2O2 (data not shown). The illustrated mass spectrum was obtained from cleavage product formed in the presence of all of Zn2+/Mn2+/Mg2+. The same cleavage products were observed upon reaction in the presence of Zn2+/Mg2+ without Mn2+ (data not shown).
