Scheme of the central carbon metabolism and glutamate biosynthesis and relative RNA levels with/without ciprofloxacin treatment. Genes are depicted next to the reaction catalyzed by the encoded enzymes. Relative RNA levels of cells treated with 4 µg/ml ciprofloxacin compared to untreated cells are shown (values in green are below 1, those in red greater than 1), however, unlike the genes listed in Table 2, none of the genes depicted here showed significantly changed expression as determined by Student’s t-test, i.e., p > 0.05. 6PGL: 6-phosphogluconolactone; 6PG: 6-phosphogluconat
