Figure 5From: Study of the role of Mce3R on the transcription of mce genes of Mycobacterium tuberculosisEffect of Mce3R on its own transcription during in vitro growth of M.tuberculosis. Comparison of mce3R promoter activity during the growth of Δmce3R (pPR3-lacZ) (white bars) and H37Rv (pPR3-lacZ- Mce3R endogenous) (grey bars) strains in M7H9-AD-G medium. The results are presented as β-galactosidase activity expressed as Miller units ± S.D. of duplicate in three time points (1 early exponential phase, 2 exponential phase and 3 stationary phase). Growth curves of Δmce3R (pPR3-lacZ) (circle) and H37Rv (pPR3-lacZ- Mce3R endogenous) (rhombus) strains are shown and the OD 600nm values are indicated on the right. Results represent one of three independent experiments.Back to article page
