Multicopy CUP1 plasmids enhance cadmium and copper resistance levels in yeast.

Molecular & general genetics : MGG - 1 Mar 1991

Jeyaprakash A, Welch J W, Fogel S

Abstract excerpt

A 3.3 kb fragment of yeast genomic DNA was isolated by screening a genomic library constructed in the high copy number 2 micron plasmid YEp351 vector for clones capable of enhancing the degree of resistance of Saccharomyces cerevisiae strain MW3070-8B to cadmium. The insert contained two complete copies of the CUP1 gene open reading frame (183 bp), including the upstream promoter sequences (450 bp) with two...
