Figure 5. Mtb growth is sensitive to elevated PknB levels.

Figure 5

(A) Overexpression of PknB by the tet-pknB mutant upon induction with ATc. PknB levels were determined by Western blot using PknB-specific rabbit IgG and anti-FLAG antibody. (B) Effects of PknB overexpression measured by CFU for 6 d post-ATc induction and by (C) optical density in comparison to the kinase dead mutant tet-pknB K40A. (Inset) PknB expression in the tet-pknB and tet-pknB K40A mutants was determined by anti-FLAG Western Blot. 1, wild type; 2, tet-pknB; 3, tet-pknB K40A, all treated with 20 ng/ml ATc. Error bars represent standard deviation.
