Zn(2+)-Dependent Deoxyribozymes That Form Natural and Unnatural RNA Linkages

We report Zn(2+)-dependent deoxyribozymes that ligate RNA. The DNA enzymes were identified by in vitro selection and ligate RNA with k(obs) up to 0.5 min(−1) at 1 mM Zn(2+) and 23 °C, pH 7.9, which is substantially faster than our previously reported Mg(2+)-dependent deoxyribozymes. Each new Zn(2+)-...
