Table 2.
Substrate | Kact (μM nucleotides) | kcat (s−1) |
---|---|---|
Oligonucleotides (dTn) | 0.4±0.2 | 38±2 |
Poly dT | 0.14±0.02 | 32±1 |
M13 ssDNA | 0.27±0.04 | 38±2 |
Poly dA | 0.22±0.03 | 51±2 |
The parameters values for Kact and kcat were determined from a fit of equation 1 to the data in Figure 2 and Figure 3. For the DNA oligonucleotides, the Kact value reported is the average for all lengths above 12 nucleotides. All values reported are best fit values with the standard deviation from NLLS fitting.
