Bacterial toxins.
Many bacterial toxins are proteins, encoded by the bacterial chromosomal genes, plasmids or phages. Lysogenic phages form part of the chromosome. The toxins are usually liberated from the organism by lysis, but some are shed with outer membrane proteins in outer membrane vesicles. An important non-protein toxin is lipopolysaccharide or endotoxin, which is a constituent of the cell wall of gram ...
متن کاملBinary bacterial toxins: biochemistry, biology, and applications of common Clostridium and Bacillus proteins.
Certain pathogenic species of Bacillus and Clostridium have developed unique methods for intoxicating cells that employ the classic enzymatic "A-B" paradigm for protein toxins. The binary toxins produced by B. anthracis, B. cereus, C. botulinum, C. difficile, C. perfringens, and C. spiroforme consist of components not physically associated in solution that are linked to various diseases in huma...
متن کاملParalytic Shellfish Poisoning Toxins: Biochemistry and Origin
Plankton feeders such as bivalves often become toxic. Human consumption of the toxic bivalve causes severe food poisoning, including paralytic shellfish poisoning (PSP) which is the most dangerous because of the acuteness of the symptoms, high fatality and wide distribution throughout the world. Accumulation of PSP toxins in shellfish has posed serious problems to public health and fisheries in...
متن کاملBacterial toxins deliver the goods.
Some toxins produced by bacteria are so potent that scientists have long considered putting them to good use. This became possible when their structures were determined through the combined use of molecular biology and structural biochemistry. The current status of targeted toxin technology is perhaps best illustrated by exotoxin A produced by Pseudomonas aeruginosa, a Gram-negative bacterium t...
