The activation of the crp promoter by Cra. The chromosomal Pcrp-lacZ fusion at the lac locus was made. MG1655ΔlacY and MG1655ΔlacYΔfruR cells containing the Pcrp-lacZ fusion were cultured in M63 with 0.5% (w/v) of various carbon sources. For β-galactosidase assays, samples were collected during the exponential growth phase (first two columns) and the stationary phase (last two columns). For brevity, wt = MG1655ΔlacY; ΔfruR = MG1655ΔlacYΔfruR.
