FIG. 5.

Effects of the hns651mutation on hisJ, cysP, srlE, and garP transcription. The bars indicate relative levels of expression measured in the wild-type strain DL1504 (wt) and in the hns651 mutant strain DL1947 (hns651). Relative levels of expression are expressed in comparison to the wild-type strain grown in M9 glycerol medium at 37°C. A bracket indicates a statistically significant difference in expression levels based on temperature under the given condition and is accompanied by the ratio of expression (37°C/23°C). Error is expressed as ±1 standard deviation from the mean.
