catalyze the hydrolysis of phosphodiesters. The active site on the surface of the folded catalyst is composed of two histidine and four arginine residues, with the capacity to provide general acid, generalbase, and/or nucleophilic catalysis as well as transition state stabilization. Uridine 3'-2,2,2 trichloroethylphosphate (2) is a mimic of RNA with a leaving group pKa of 12.3. Its hydrolysis is energetically
