Figure 6. Mtb ΔglpXΔgpm2 fails to grow on gluconeogenic carbon sources and lacks detectable FBPase activity.

Figure 6

(a) Growth of WT Mtb (black), ΔglpX (red), ΔglpXΔgpm2 (orange) and complemented strains ΔglpXΔgpm2/C (glpX) (purple) and ΔglpXΔgpm2/C (gpm2) (blue) in Sauton's minimal media containing no carbon source, 0.4% glucose, 0.1% glycerol or 0.1% butyrate. Data are representative of three independent experiments. (b) FBPase activity of WT Mtb (black), ΔglpX (red), ΔglpXΔgpm2 (orange) and complemented strains ΔglpXΔgpm2/C (glpX) (purple) and ΔglpXΔgpm2/C (gpm2) (blue) cell lysates in the absence or presence of lithium chloride using 1.5 mM FBP or 12 mM FBP as substrate. ND indicates no detectable FBPase activity. Dashed line indicates limit of detection. Data are means ± standard deviation of three biological replicates.
