Research output: Contribution to journalArticlepeer-review


Mn2+ and Mg2+ uptake was studied in a wild type strain of S. cerevisiae and in a mutant resistant to Mn2+. Contrary to expectations, the resistant strain accumulates Mn2+ to a higher concentration than the wild type strain, while Mg2+ uptake is unaffected. Moreover, the transmembrane electric potential (PD) of the resistant strain is far less depolarized by Mn2+ than that of the sensitive strain. A possible explanation for these results is discussed.
