FIGURE 4.

A, specific β-galactosidase activity of D39 WT (wt), D39 ΔargR1 (R), D39 ΔahrC (C), and D39 ΔargR1ΔahrC (RC) containing PabpA-lacZ (abpA), PartP-lacZ (artP), PaapA-lacZ (aapA), PabpB-lacZ (abpB), and PaliB-lacZ (aliB) transcriptional fusions. Cells were grown in GM17 medium (black bars) and in CDM with 10 (gray bars) or 0.025 (white bars) mm arginine and harvested at the midexponential phase of growth. Data are the averages of at least three measurements. p values were <0.005 for the comparisons between 10 and 0.025 mm arginine in the wild type for each of the lacZ fusions as calculated with the Student's t test. B, specific β-galactosidase activity of D39 WT (wt) and D39 ΔargR1 (R) containing PabpA-mut-lacZ (abpA-mut), PartP-mut-lacZ (artP-mut), PabpB-mut-lacZ (abpB-mut), and PaliB-mut-lacZ (aliB-mut) transcriptional fusions. Cells were grown in CDM with 10 (gray bars) or 0.025 (white bars) mm arginine and harvested at the midexponential phase of growth. Data are the averages of at least three measurements, and error bars represent the standard deviation.
