Progress towards synthetic enzymes for phosphoester hydrolysis.

Synthesis of artificial enzymes for catalyzing phosphoester hydrolysis has been attracting interest for a long time. The remarkable discovery that lanthanide ions catalyze the hydrolysis of DNA and RNA spurred the trend. Currently, progress is being made, mainly in the preparation of homogeneous catalysts, the promotion of catalytic activity by using acid/base cooperation within catalysts, the detailed understanding of the reaction mechanisms involved, and the design of artificial enzymes expressing high specificity and catalytic turn-over.
