title: Hydrolytic approach for production of deoxyribonucleoside- and ribonucleoside-5 -monophosphates and enzymatic synthesis of their polyphosphates.
abstract: A new, simple, and ingenious method for enzymatic synthesis of deoxy- and ribonucleoside-5 -triphosphates (dNTP and NTP, respectively) has been developed. The method includes the following stages: hydrolysis of DNA with DNase and immobilized S1-nuclease, phosphorylation of the resulting deoxy- and ribonucleoside-5 -monophosphates (dNMP and NMP, respectively) with nucleotidyl kinase from Escherichia coli, and purification by chromatography of the synthesized dNTP and NTP. dNMP was phosphorylated using an ATP-regenerating system based on acetokinase from E. coli and lithium acetylphosphate.
