Examples of metal-specific DNAzymes. (A) Mg2+-dependent “10–23” DNAzyme with RNA nuclease activity; B) Pb2+-dependent “8–17” DNAzyme with RNA nuclease activity; C) Cu2+-dependent DNAzyme with ligase activity; and D) DNAzyme that catalyzes porphyrin metallation. The letter “N” in the sequence represents any nucleotides capable for forming Watson-Crick base pairs. R=A or G, Y=C or T.
