Enables the directed movement of substances (such as macromolecules, small molecules, ions) into, out of, within or between cells. Enables the transfer of a substance from one side of a membrane to the other. This is a type of carrier produced by bacteria. It enable passive transport by shielding the ion that is being transported from the lipid membrane. It carries an ion across the membrane by enclosing the ion and travelling across the membrane. It does not form a fully open pore across the membrane. Catalysis of energy-independent facilitated diffusion, mediated by passage of a solute through a transmembrane aqueous pore or channel. Stereospecificity is not exhibited but this transport may be specific for a particular molecular species or class of molecules. Catalysis of the transfer of a solute from one side of the membrane to the other, down the solute's concentration gradient.
