| Organism | Growth pH | Glucose PTS activitya | Fold induction |
|---|---|---|---|
| S. sobrinus 6715 | 7.0 | 83 (±30) | 1.0 |
| 5.0 | 129 (±44) | 1.6 | |
| S. sobrinus SL1 | 7.0 | 73 (±38) | 1.0 |
| 5.0 | 197 (±88) | 2.7 | |
| S. mutans UA159 | 7.0 | 84 (±35) | 1.0 |
| 5.0 | 42 (±17) | 0.5 |

The values are the means (standard deviations) of at least three independent experiments. PTS activity is expressed as nanomoles of NADH oxidized in a PEP-dependent manner per minute per milligram of protein.
