Steady state kinetics and (15)N isotopeeffects have been used to study the cyclization reaction of uridine 3'-p-nitrophenyl phosphate. The cyclization reaction is catalyzed by transition metal ions and lanthanides, as are substitution reactions of many phosphateesters. Kinetic analysis reveals that the erbium-catalyzed cyclization reaction involves the concerted deprotonation of the 2'-OH group and departure
