Nucleotidyl transferring enzymes, role

Phosphoryl and nucleotidyl transfer enzymes are extremely important and widespread in biology. They have in common the catalysis of nucleophilic reactions of phosphorus esters, and the general requirement for divalent metal ions, particularly Mg11, for activity. This requirement has stimulated considerable interest in the catalytic roles of divalent metal ions in these reactions. [Pg.443]

This article will consider recent advances in the mechanism of model phosphoryl transfer reactions, magnetic resonance studies of phosphoryl and nucleotidyl transerring enzymes in solution and Xray diffraction studies in the crystalline state which have clarified or at least have suggested the role of the essential divalent cation. [Pg.2]

Mildvan and Grisham have reviewed the role of bivalent cations in the mechanism of enzyme-catalysed phosphoryl and nucleotidyl transfer reactions. [Pg.281]
