Table 1. Summary of phenotypic analysis of recA mutants used in this study.
Strain | recAo | recA | % Recombinants per 100 donors | % Surviving 5 J/m2 of UV | SOS expression ratio after 5 J/m2 of UV |
SS996 | + | + | 1.09±0.26 | 80.0±3.8 | 8.7±2.8 |
SS391 | + | 938::cat | 0.0006±0.0002 | <0.001 | ND a |
SS4629 | + | 730 | 1.50±0.14 | 78.0±2.0 | ND |
SS6013 | + | 4142 | 1.79±0.34 | 87.8±6.3 | 11.1±1.8 |
SS4976 | 1403 | 4142 | 1.11±0.28 | 83.1±5.6 | ND |
ND is Not Determined because the cells are already fully induced for SOS expression.
