TABLE 2.
Comparison of relative potencies of various promoters in B. anthracis background
| Promoter | Strain of origin | Relative potency in B. anthracisa |
|---|---|---|
| Ppag | B. anthracis | 1 |
| Pamy | B. amyloliquefaciens | 7 |
| P43 | B. subtilis | 20 |
| Psapshort | B. anthracis | 40 |
| Psaplong | B. anthracis | 55 |
| Pntr | B. anthracis | 500 |
a
The potencies of all promoters (except the native Ppag) were determined by intensities of fluorescence in quantitative assays (see Materials and Methods). Actual values for computation were derived from Fig. 3 and 4 (stationary-phase cultures). The ratio between Ppag and Pamy was determined by PA expression.
