Mutations of D75 and D501 maintain channel functionality with only small changes in the kinetics. a, c, d, f Mean current-voltage (IV) curves and standard deviation calculated from data obtained from at least three different oocytes. b, e, g Currents measured at -145 mV at the beginning (dark grey) or end (white) of voltage pulses and of average currents over the whole voltage pulse (light grey) of D75A and D75N (b), D501A (e) and D501N (g). Currents were normalized to currents measured in Na30K1 solution. Means and standard deviations were obtained from data of three to five different oocytes
