FIG. 7.

Exogenous copper inhibits growth of YPH925 pos5. Growth rates of wild-type YPH925 (black squares) and YPH925 pos5 (open circles) cultures were measured spectroscopically at OD₆₀₀. Cells were grown in YPD supplemented with 25 μM CuSO₄, as described in Materials and Methods. Data points are averages of two independent experiments.
