Potassium ion efflux induced by cationic compounds in yeast

open access: yesBiochimica et Biophysica Acta (BBA) - Biomembranes, 1999
Potassium efflux in yeast induced by several cationic compounds showed different characteristics. All of the observed efflux required glucose as substrate at the concentrations used. For most of them, the phenomenon required binding of the cationic compound to the cell surface and increased with the negative cell surface charge, and for all the ...
