Cover Story: Yeasts need a lot of potassium to grow. The main K+ uptake system Trk1 has been shown to exist in low- or high-affinity modes according to the K+ availability, but when and how the affinity changes remains unknown. Here, we characterize the Trk1 kinetic parameters under various conditions and find that Trk1’s KT and Vmax change gradually. This gliding adjustment is rapid and controlled by changes in intracellular potassium content and membrane potential. The introduction of mutations to four specific structural segments (P-helices) of Trk1 showed the importance of two P-helices for the transporter’s transition to a high-affinity state, as well as the importance of the other two for proper Trk1 folding and activity at the plasma membrane.
