Motility of E. coli strains expressing wild-type or mutated CAP protein on semisolid agar plates
| Strain genotype | Plasmid (protein) | Motilitya |
|---|---|---|
| Wild-type | None | 30 ± 3 |
| crp::Sm | None | 3 ± 1 |
| crp::Sm | pDCRP (CAP) | 21 ± 2 |
| crp::Sm | pDCRP-T158A (mutated CAP) | 3 ± 1 |
| crp::Sm | pDCRP-H159L (mutated CAP) | 3 ± 1 |
Expressed as the diameter of the swarming ring (in millimeters) after 15 h at 30°C. The data are the mean values ± standard deviations of three independent experiments.
