Abstract

In vitro reaction conditions have been determined for the maximal synthesis of product ribonucleic acid by the influenza (WSN) virion ribonucleic acid polymerase. The reaction requires the presence of all four triphosphates, Mg 2+ and Mn 2+ ions, monovalent cations, nonionic detergent, and ribonucleoside triphosphates at concentrations above certain threshold values. The optimum p H for the reaction is around 8.0 to 8.2 and the kinetics of product synthesis are linear through at least 6 hr when incubated at 31 to 33 C.
