Exotoxins are proteins or polypeptides, and most of them act at tissue site which is away from the original point of bacterial growth or invasion. Exotoxin. Exotoxins are mostly proteins or polypeptides. As is evident from their proteinaceous nature, they are required to be synthesized inside the bacterial cell and then secreted to … Exotoxin, a poisonous substance secreted by certain bacteria. 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.
