title: 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 approximately 7.0 and at 41 degrees 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.
