Specific effect of magnesium ion on 2′, 3′-cyclic amp synthesis from adenosine and trimeta phosphate in aqueous solution

Abstract
Phosphorylation of adenosine by trimetaphosphate was investigated using various catalysts in aqueous solution under mild conditions at pH ∼ 7.0 and at 41 °C. The product was primarily 2′,3′-cyclic AMP together with smaller amounts of ATP. Magnesium ion was found to have a remarkable catalytic effect of approximately one hundred times greater than the other chemicals tested. The mechanism for the specific effect of magnesium ion is discussed.
