Intracellular ATP and ADP concentrations and the calculated energy charges for strains C. glutamicum HIS1–HIS7 with C. glutamicum ATCC 13032 (WT) as reference. Intracellular ATP and ADP contents from exponentially growing cells in μmol gCDW−1 are shown in dark gray and white, respectively. Energy charges are shown as light gray and have been calculated without considering AMP, since AMP concentrations in the histidine producing strains were below the detection limit of the applied HPLC system (see “Methods”). Experiments were performed in at least triplicates and standard deviations are given as error bars
