Abstract excerpt
TRK1, the gene encoding the high affinity K+ transporter in Saccharomyces cerevisiae, is nonessential due to the existence of a functionally independent low affinity transporter. To identify the gene(s) encoding the low affinity K+ transporter, we screened trk1 delta cells for mutants (Kla-) that require higher concentrations of K+ in the medium to support growth. trk1 delta trk2 mutants require up to tenfold...
