Fig. 5: Inactivation kinetics of AtHAK5.
From: Arabidopsis HAK5 under low K+ availability operates as PMF powered high-affinity K+ transporter
A Representative current traces from oocytes co-expressing AtHAK5 and CIPK23/CBL1 at −120 mV when challenged with different K+ concentrations (as indicated in the figure) for 120 s. B Degree of inactivation (in %) derived from similar experiments as shown in A) were plotted against the applied K+ concentration (n = 3 experiments, mean ± SD). C Representative current response of AtHAK5/CIPK23/CBL1 co-expressing oocytes at pH4.5, pH5.5 or pH6.5 upon application of either 20, 200 or 2000 µM K+. D Box plot of the percentage of inactivation derived from similar experiments as shown in C) (number of experiments is indicated in the figure).
