Effect of RNA on the ATPase activity at different concentrations of NS3h.

<p>Initial rates of phosphate release (<i>vi</i>) were obtained in the absence (♦) and in the presence of poly(C): 0.50 M () or 3.1 M (). ATP concentration was 0.10 mM and reactions were carried out in the same reaction media as were indicated above (see Materials and Methods). Data showed in (a) as a function of [NS3h] are plotted in (b) as a function of the ratio [poly(C)]/[NS3h].
