Effects of CRP deletion at rhaSR
| Promoter fusion | β-Galactosidase sp acta
|
|
|---|---|---|
| crp+ | Δcrp | |
| Φ(rhaS-lacZ)Δ216 | 90 | 0.9 |
| Φ(rhaS-lacZ)Δ128 | 136 | 1.7 |
| Φ(rhaS-lacZ)Δ90 | 1.2 | 1.0 |
β-Galactosidase specific activity was measured from single-copy rhaS-lacZ fusions in a wild-type crp or crp deletion strain. Cultures were grown in MOPS media containing fructose, l-rhamnose, and 2 mM cAMP. Standard errors were less than 24% of the average units.
