DNA-catalyzed glycosylation using aryl glycoside donors

Abstract

We report the identification by in vitro selection of Zn(2+)/Mn(2+)-dependent deoxyribozymes that glycosylate the 3'-OH of a DNA oligonucleotide. Both β and α anomers of aryl glycosides can be used as the glycosyl donors. Individual deoxyribozymes are each specific for a particular donor anomer.
