摘要
The chemical ligation of DNA molecules can be mediated by terminal phosphorothioate displacement of a 5' iodine. We have selected deoxyribozymes that can catalyze the formation of such phosphorothioester internucleotide linkages. The selected deoxyribozymes enhance the rate of ligation in part through the provision of a template that aligns the ligation junction and do not appear to require metal ions for catalysis.
