  1. 1Higher molecular weight products (12-, 13- and/or 14 mers) were observed, but data not included to estimate single turnovers.
  2. 2Data over 500 nM omitted.
  3. 3So few data points were available that there was no standard error for the single exponential calculations. In some cases, incorporation was so inefficient that data did not resemble a single exponential. Therefore, zero and the highest datapoint were used, yielding no standard error.
