Promoter activities of various lacZ transcriptional fusionsa
| Vector or lacZ fusion | β-Galactosidase activity (Miller units) |
|---|---|
| Vector | 0.3 ± 0.1 |
| yghJ-lacZ | 135 ± 15 |
| pppA-lacZ | 34 ± 5 |
| yghG-lacZ | 16 ± 4 |
| gspC-lacZ | 0.8 ± 0.1 |
| gspD-lacZ | 1.1 ± 0.3 |
E. coli MC4100 derivatives carrying different lacZ fusions were grown in Luria broth at 37°C. β-Galactosidase activity is the mean ± standard deviation of three independent experiments.
