Enables the directed movement of substances (such as macromolecules, small molecules, ions) into, out of, within or between cells. Enables the directed movement of a toxin into, out of, within or between cells. A toxin is a poisonous compound (typically a protein) that is produced by cells or organisms and that can cause disease when introduced into the body or tissues of an organism. Enables the transport of a solute across a membrane via a large pore, un-gated channel. Examples include gap junctions, which transport substances from one cell to another; and porins which transport substances in and out of bacteria, mitochondria and chloroplasts. Enables the energy independent passage of toxins, sized less than 1000 Da, across a membrane towards the outside of the cell. The transmembrane portions of porins consist exclusively of beta-strands which form a beta-barrel. They are found in the outer membranes of Gram-negative bacteria, mitochondria, plastids and possibly acid-fast Gram-positive bacteria. Catalysis of the transfer of substances, sized less than 1000 Da, from one side of the membrane to the other. The transmembrane portions of porins consist exclusively of beta-strands which form a beta-barrel. They are found in the outer membranes of Gram-negative bacteria, mitochondria, plastids and possibly acid-fast Gram-positive bacteria.
