For a metal ion at a catalytic site of an enzyme, the electrophilic behavior of the ion will depend on the nature of the ligands and to some extent on the ge- 

Metal Ion Dissociation Constants of Sites WT, Q142N, Q142E, and Q142D  

A series of kinetic experiments reported by Herschlag and Jencks (7) addressed the influence of metal ions on phosphoryl transfer reactions for non-enzymic phosphoryl transfer between pyridine and carboxylate ions (and other nucleophiles). The reaction of actetate ion with phosphorylated -y-picoline monoanion and the reverse reaction of y-picoline with acetyl phosphate dianion are
