This simplicity appears to be an advantage when artificial RNases are used in design of therapeutics for controlling gene expression or as components of synthetic conjugates. These conjugates are targeted to specific RNA molecules by oligonucleotides, and unwanted interactions of their componen

For nucleic acids cleaving enzymes it is suggested that hydrolysis of p-o bonds passes via acid-base catalysis (delCardayre and Raines 1995). In contrast to hydrolysis of c-o bonds, the p-o bonds are very rarely cleaved via nucleophilic catalysis (Gottlin et a

These cleavage reagents have also been tethered to larger molecules such as oligonucleotides, proteins, and intercalating agents, which confer additional specificity. This review will focus on the 1,1O-phenanthroli

The efficiency of hydrolysis is determined by the catalytic properties of active groups, and the specificity is determined by the affinity of compounds for certain RNA sites.
