Other Oligonucleotide Modifications Catalyzed by DNAzymes

In contrast, RNA ligation by DNAzymes has been well documented [81]. The first Ca or Mg -dependent system gave nucleophilic opening of the 2 -3 cyclic phosphate of one RNA strand by the 5 -hydroxyl group of the other, resulting in an 

Other modification reactions of (ohgo)nucleotides catalyzed by DNAzymes include kinase (5 -phosphorylation) [89-92], DNA capping [93], self-depurination [94], and RNA tagging [95].
