|
||
---|---|---|---|---|
−61 to +50 | −88 to +50 | −154 to +50 | ||
Wild type | 1.29 | 2,297 (1.0) | 8,811 (3.8) | 10,822 (4.7) |
rpoCΔ215–220 | 1.14 | 608 (1.0) | 5,152 (8.5) | 8,927 (14) |
rpoBRH454 | 1.05 | 716 (1.0) | Not done | 7,036 (9.8) |
Results are means from two or three experiments; the variation was less than 10%. The promoter activity relative to −61 to +50 in each strain background is given in parentheses.
