Heterologous Expression of MTP2 in Yeast Mutants.
Heterologous expression of the MTP2 cDNA can rescue the Zn-sensitive yeast mutant zrc1 cot1, but not the Cd-sensitive ycf1 or the Fe-sensitive ccc1 mutants. Serial 1:10 dilutions are shown from left to right for S. cerevisiae wild type (BY4741), mutant transformed with empty vector pFL61 (ev), and mutant transformed with MTP2.
