FIG. 7 — Expression of citZ-lacZ and citB-lacZ fusions in citB and citZAB mutants. citB strains carrying citZ-lacZ (LAB2907) and citB-lacZ (LAB2905) fusions and citZAB strains carrying citZ-lacZ (LAB2935) and citB-lacZ (LAB2936) fusions were grown as described in the legend to Fig. 2 under aerobic (open circles) and anaerobic (closed circles) conditions. Also shown are endogenous β-galactosidase activities (β-gal. act.) of JH642, which carries no lacZ fusion, during aerobic (open circles) and anaerobic (closed circles) growth.
