Pre-steady-state rate constants for post-EFdA incorporation of a single dCTP (the next correct nucleotide) by RT and pol γa.
| Enzyme | kpol (s−1) | Kd (μM) | Efficiencyb (μM−1 s−1) |
|---|---|---|---|
| RT | 0.0064 ±0.0004 | 1.9 ± 0.4 | 0.0034c |
| pol γ | ≤0.0002d | N. D. | N. D. |
Kinetic parameters determined from nine (RT) or seven (pol γ) single turnover experiments with varying dCTP concentrations.
N.D.: not determined.
Incorporation of dCTP after AMP in a similar primer/template has a measured efficiency of 1.5 μM−1 s−1 (Kim et al., 2012).
Incorporation of dCTP after AMP in a similar primer/template has a measured kpol of 72 ± 3 s−1 (Sohl et al., 2013).
