Practical Enzymatic Synthesis of Adenosine 5'-O-(3-Thiotriphosphate) (ATP-γ-S)

Article abstract of DOI:10.1021/jo00182a009

An enzymatic procedure for the synthesis of adenosine 5'-O-(3-thiotriphosphate) (ATP-γ-S) on a 50-mmol scale from dihydroxyacetone, sodium thiophosphate, ADP, and phosphoenol pyruvate is described.The synthesis uses polyacrylamide gel immobilized glycerokinase coupled to a pyruvate kinase catalyzed ATP cofactor regeneration system, and polyacrylamide gel immobilized triosephosphate isomerase, glyceraldehyde 3-phosphate dehydrogenase, and phosphoglycerate kinase coupled to a lactate dehydrogenase catalyzed NAD cofactor regeneration system.The ATP-γ-S is purified by adsorption on Dowex 1 and isolated as the sodium or barium salts in ca. 90 percent purity.
