Because they are enzymatic proteins that act catalytically to kill cells, bacterial and plant toxins are often employed as the cell-killing component of immunotoxins. Here we provide background information into the structure-func­ tion relationships of toxins and discuss how they can be combined with cell-binding antibodies or other ligands to generate immunotoxins. Bacterial and plant toxins (e. g. , diphtheria toxin, Pseudomonas exotoxin and ricin) are among the most toxic substances known. However, because they bind to cell surface receptors that are present on most normal cells, unmodified toxins are generally useless as anti-cancer agents. To convert toxins into more selective agents, their binding domains are either eliminated or disabled and replaceq with cell­ binding antibodies that are tumor-selective.
