Table 2. ssDNA-dependent ATPase activity of PcrA and UvrD.
Protein | ATPase (s−1)a |
---|---|
Wild type PcrA | 12.1 ± 0.8 |
PcrA K712A | 15.8 ± 0.7 |
PcrA L714A | 18.9 ± 1.8 |
Wild type UvrD | 81.1 ± 3.0 |
UvrDΔC | 194.9 ± 7.5 |
UvrD K708A | 82.8± 19.8 |
aATP hydrolysis was measured using a coupled assay as described in the Materials and Methods under conditions of saturating ATP and ssDNA. The values reported are the mean turnover number and the standard error of the mean for three independent experiments.
