(a) Copper and (b) cadmium tolerance evaluated by phenotype rescue on DTY4 [metallothionein (MT) deficient] yeast cells. Metal tolerance of each DTY4 strain transformed with different MTs, as indicated in the side boxes, is shown as a percentage of the growth rate exhibited in a non-metal-supplemented medium. Cup1 and Crs5 are the two yeast MTs, and MT1 stands for the mouse MT1 isoform.
