In their purest form they are the most potent poisons known and are the active agents in diphtheria, tetanus, and botulism. The term is now sometimes restricted to poisonous proteins that are antigenic— i.e., that stimulate the formation of antibodies—and formed by gram-positive bacteria. Exotoxin A is an extracellular enzyme that is produced by most clinical strains of Pseudomonas aeruginosa. It is a single-chain polypeptide (molecular weight, 71,000) with A and B fragments that mediate enzymatic and cell-binding functions, respectively. Exotoxin A catalyzes the transfer of the aden ….
