Effect of recB, recF, and recR mutations on luciferase response ratio from SOS induction by mutant topoisomerase I cleavage complex
| Strain | Luciferase response ratioa
|
|
|---|---|---|
| YTOP128 | YTOP-G122S | |
| BW27784 | 4.7 | 3.5 |
| YT102 (recB) | 0.91 | 0.96 |
| JHS2 (recF) | 4.1 | 3.4 |
| JHS3 (recR) | 4.4 | 3.9 |
Luciferase response ratio was measured as the ratio of luminescence measured at 260 min after the addition of 0.00006% arabinose versus the luminescence from control cultures not treated with arabinose.
