Potassium Starvation in Yeast: Mechanisms of Homeostasis Revealed by Mathematical Modeling
Figure 4
Relationship of external and internal potassium.
(A) Cells grown in 50 mM KCl were resuspended in 0.1, 0.2 and 0.5 mM KCl and the time course of internal potassium was monitored. The lines show the data fit obtained from the reverse tracking algorithm. (B) Internal potassium concentration in cells grown overnight at different external potassium concentrations. The steady state concentrations from (A) are indicated as squares.
