Figure 7

Pi efflux from exponential phase cells exposed to copper. 6 h MT (black bars) or MT + P (grey bars) cells of the indicated strains were resuspended in T buffer and exposed to 0.25 mM Cu2+ during different times. Pi was quantified in supernatants as described in Methods. Data are expressed as average ± SD of three independent experiments.
