Growth phase-dependent expression of a citB-lacZ fusion in wild-type and codY, ccpC, and abrB mutant strains. β-Galactosidase activity was measured in wild-type and mutant strains sampled at various times during growth in DS medium. Arrows indicate the end of the exponential growth phase. (A) Strains: AF21 (wild type [wt]), HKB95 (codY), CJB9 (ccpC), HKB98 (codY ccpC), and HKB99 (codY ccpC abrB). (B) Strains: AF21 (wild-type), HKB94 (abrB), HKB95 (codY), HKB96 (abrB codY), and HKB99 (codY ccpC abrB). (C) Strains: AF21 (wild-type), CJB9 (ccpC), HKB94 (abrB), and HKB97 (ccpC abrB).
