| Relative mRNA levels* | ||
|---|---|---|
| Strain | arsA | arpR |
| UW136 | 1.0 ± 0.0 | 1.0 ± 0.0 |
| PtsP | 0.043 ± 0.007 | 0.021 ± 0.003 |

| PtsN | 2.07 ± 0.24 | 2.7 ± 0.16 |
| ptsP-ptsN | 1.62 ± 0.10 | 1.3 ± 0.11 |
*The mRNA levels of arsA and arpR in pts mutants are relative to showed by UW136 strain, which are assumed to be 1.0. The values are the mean of two independent experiments.
