Voltage dependency of PA₆₃-channels in the presence of EDIN and His₆-EDIN.

<p>A: Current response of PA₆₃-channels in presence of EDIN. Voltage pulses between +20 and +70 mV were applied to a diphytanoyl phosphatidylcholine/n-decane membrane in the presence of PA₆₃-pores and EDIN (both added only to the cis side of the membrane). The aqueous phase contained 150 mM KCl, 10 mM MES-KOH, pH 6. The temperature was 20°C. B: Current response of PA₆₃ channels in the presence of His₆-EDIN. Voltage pulses between +10 and +90 mV were applied to a diphytanoyl phosphatidylcholine/n-decane membrane in the presence of PA₆₃-pores and His₆-EDIN (both added only to the cis side of the membrane). The aqueous phase contained 150 mM KCl, 10 mM MES-KOH, pH 6. The temperature was 20°C. Note the change of the scale (Arrow).
