A study of the activity of deoxyribonucleotide-substituted analogs of the hammerhead domain of RNA catalysis has led to the design of a 14mer oligomer composed entirely of deoxyribonucleotides that promotes the cleavage of an RNA substrate. Characterization of this reaction with sequence variants and mixed DNA/RNA oligomers shows that, although the all-deoxyribonucleotide oligomer is less efficient in catalysis, the DNA/substrate complex shares many of the properties of the all-RNA hammerhead domain such as multiple turnover kinetics and dependence on Mg2+ concentration. On the other hand, the values of kinetic parameters distinguish the DNA oligomer from the all-RNA oligomer. In addition, an analog of the oligomer having a single ribonucleotide in a strongly conserved position of the hammerhead domain is associated with more efficient catalysis than the all-RNA oligomer.
