Predictions of the model for ionic currents in symmetrical 120 mM K⁺ at room temperature (19–20°C) for 4wt, 2wt/2mut, and 1wt/3mut compared with experimental data. Experimental data are shown on the left, and the right panel illustrates the predictions of the kinetic model illustrated in Scheme 1. The artifacts of pulse subtraction and compensation measured at the beginning of the pulses (first ms) are not shown. The HP was −90 mV, and steps were elicited to the annotated V_m. The rate constants and equivalent valence in electronic charge units are shown in Table I.
