Fig 8. The linkage between creD inactivation and σ^E-mediated envelope stress response.

The promoter transcriptional fusion constructs of rpoE and smeI genes, pRpoE_xylE and pSmeI_xylE, were transferred into KJ, KJΔCreD, and KJΔCreDΔRpoE cells and the expressed C23O activities were determined, respectively. Each bar represents the mean of three independent experiments. Error bars indicate the average deviation. *, p≤0.01 significance calculated by s Student’s t-test.
