obsolete pore-forming toxin activity (obsolete GO:0015289)
OBSOLETE. Catalysis of the transport of electrolytes and other small molecules across a cell membrane. They are synthesized by one cell and secreted for insertion into the membrane of another cell where they form transmembrane pores. They may exert their toxic effects by allowing the free flow of electrolytes and other small molecules across the membrane, or they may allow entry into the target cell cytoplasm of a toxin protein that ultimately kills the cell.
