The invention is directed to a method for altering the ion conductivity of a membrane. The method comprises inserting a biological photoreceptor into the membrane. The biological photoreceptor is configured to act as a light-controlled ion channel. The photoreceptor used comprises an apoprotein and a light-sensitive polyene covalently bound to the apoprotein, wherein the polyene interacts with the apoprotein and functions as a light-sensitive gate. |
