Fig. 5From: An extracellular cation coordination site influences ion conduction of OsHKT2;2Mutation of P71 does not affect channel functionality. a Mean current-voltage (IV) curves and standard deviation calculated from data obtained from at least three different oocytes. b Representative currents measured at the indicated NaCl and KCl concentrations in Xenopus laevis oocytes two days after cRNA injection. A pulse at holding potential (zero current level) was followed by 1 s voltage pulses from +20 to -160 mV in -15 mV decrements and continued with a final pulse at holding potential for 1.5 sBack to article page
