Using a combination of physiological, biochemical and proteomic approaches, we show that during growth at suboptimal potassium concentrations, double trk1,2 mutants accumulate less potassium and reach lower yields.
Title: A physiological, biochemical and proteomic characterization of Saccharomyces cerevisiae trk1,2 transport mutants grown under limiting potassium conditions.

Trk2 is the major potassium uptake system in stationary cells, and potassium content to be a crucial parameter for desiccation survival.
Title: Potassium uptake system Trk2 is crucial for yeast cell viability during anhydrobiosis.

TRK2 overexpression improved the ability of trk1 cells to grow in low K(+) and led to a higher accumulation of K(+).
Title: Trk2 transporter is a relevant player in K+ supply and plasma-membrane potential control in Saccharomyces cerevisiae.

TRK2 encodes a functional potassium ion transporter that, under specific experimental conditions, displays distinctive kinetic characteristics.
Title: The yeast potassium transporter TRK2 is able to substitute for TRK1 in its biological function under low K and low pH conditions.

Results indicate that, in addition to their role in regulating Trk1 and 2 potassium transporters, Ppz phosphatases 1 and 2 positively affect the residual low affinity potassium transport mechanisms in yeast.
Title: The Ppz protein phosphatases regulate Trk-independent potassium influx in yeast.
