Amplification of a gene for metallothionein by tandem repeat in a strain of cadmium-resistant yeast cells

Abstract In a cadmium-resistant strain of Saccharomyces cerevisiae, cells are protected against cadmium toxicity by the production of large amounts of cadmium-binding metallothionein, as occurs similarly in a copper-resistant strain. The apoprotein of the metallothionein is encoded by the CUP1 gene...
