Figure 3From: Study of the role of Mce3R on the transcription of mce genes of Mycobacterium tuberculosisEffect of Mce3R on mce3 promoter activity during the growth of M. tuberculosis. Comparison of mce3 promoter activity during the growth of Δmce3R (pP3-mce3R-lacZ) (grey bars) and Δmce3R (pP3-lacZ) (white 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 (pP3-lacZ) (square) and Δmce3R (pP3-mce3RlacZ) (circle) strains are shown and the OD 600nm values are indicated on the right. Results represent one of at least three independent experiments.Back to article page
