Zinc Channel

Caption: The twisting (blue arrows) of the red portion of the zinc ion channel allows the opening and closing of its gate. Left: the channel is open to the inside of the cell, allowing zinc (green) to flow into its binding site (pink star) after hydrogen flows out. Right: the channel is open to the outside of the cell, allowing zinc to flow out and hydrogen to flow in.
