Figure 8. Expression of cuoB in strains harboring point mutations in the CRD region of CorE.

The mutated Cys are indicated in each panel. Cells were incubated on CTT agar plates containing 0.3 mM copper (continuous lines) or without metal (dashed lines), and samples were harvested at different times to determine β-gal specific activity. Note that the scale in panel F is different from that used in the other panels. Error bars indicate standard deviations.
