Figure 1.
Time-course of self-thio-phosphorylation reactions. Product formation was monitored under the selection conditions for individual kinase ribozyme clones that had been selected in the presence of ATPγS (A) or GTPγS (B) donors. Plotted data points are the averages of three independent replicas. Kinetic parameters of each ribozyme (C) were calculated by fitting the experimental data to a first-order exponential equation.
