Specific xylulose-5-P phosphoketolase activity in crude cell extracts of C. acetobutylicum strainsa
| Strain | Sp act (mU [mg protein−1])b |
|---|---|
| ATCC 824 | 8.3 ± 1.5 |
| xfp::intron | 5.5 ± 0.8 |
| 824-pIMP1 | 9.4 ± 2.4 |
| 824-pIMP1XFP | 120 ± 10 |
Samples were harvested during exponential growth on xylose.
The average and the standard deviation were determined from three independent experiments.
