Abstract
The interaction of Mg2+ with nucleoside disphosphates : ADP, GDP, CDP and UDP has been studied by phosphorus magnetic resonance spectroscopy in aqueous solution. The results show that these four nucleotides behave similarly, the Mg2+ ion binds to the alpha but not to the beta phosphate moiety. The strength of the interaction of Mg2+ ions with nucleoside diphosphates is weaker than with nucleoside triphosphates. The association of Mg2+ on the phosphate chain is stronger in a neutral than in an acid medium.Entities:
