Table 3. Concentration of intracellular glucose-6-phosphate and fructose-6-phosphate in aerobic M. tuberculosis strains.
Glucose-6-phosphate (µmol crude protein g−1) | Fructose-6-phosphate (µmol crude protein g−1) | |||
Glucose | + | − | + | − |
WT | 31.1/29.8 | 19.3/18.5 | 7.9/6.4 | 2.6/1.9 |
Δ pfkA | 55.0/55.1 | 32.8/31.3 | 14.2/13.9 | 3.7/3.8 |
Concentration of intracellular metabolites of mid-log phase M. tuberculosis strains cultured in complete Dubos liquid medium or Dubos liquid medium without glucose. Each biological sample was measured in duplicate. The data represent the values obtained for each duplicate of each biological sample. This experiment was repeated as least once independently and comparable values and trends were observed.
