Phosphodiester cleavage
WebNeutral aqueous solutions of cerium ammonium nitrate obtained by dilution of their acetonitrile stock solution with imidazole buffer show high catalytic activity in the hydrolysis of bis(p-nitrophenyl) phosphate (BNPP) and better reproducibility than other similar systems, but suffer from low stability.The kinetics of catalytic hydrolysis is second-order in Ce(IV), … WebRibozymes are RNA composite molecules that are capable of specific phosphodiester link cleavage either of a complementary exogenous RNA fragment or of self. Therefore, like asRNAs, ribozymes have potential anti-mRNA activities that could be classified on the fringes of RNAi mechanisms.
