It also explains the toxic effects of exotoxin on host cell. For more information exotoxin: Any toxin secreted by a microorganism into the surrounding environment. cytokines: Regulatory proteins that function in the regulation of the cells involved in immune system function The Pseudomonas exotoxin (or exotoxin A) is an exotoxin produced by Pseudomonas aeruginosa. Vibrio cholerae produces a similar protein called the Cholix toxin. It inhibits elongation factor-2.It does so by ADP-ribosylation of EF2 using NAD+.This then causes the elongation of polypeptides to cease.

Exotoxins are usually heat labile proteins secreted by certain species of bacteria which diffuse into the surrounding medium. Endotoxins are heat stable lipopolysaccharide-protein complexes which form structural components of cell wall of Gram Negative Bacteria and liberated only on cell lysis or death of bacteria. Ett exotoxin är ett protein som kan skada värden genom att förstöra celler eller störa dess metabolism.

Significance of exotoxins: Most bacteria use exotoxins as virulence factors, aiding their spread and tissue damage. Some toxins actually evade immune system by damaging the cells involved in immune response or diverting immune response.

Difference Between Endotoxins and Exotoxins Toxigenesis involves production of toxins by pathogenic bacteria. It is one of the major methods of giving birth to diseases and medical disorders by bacteria. 2 categories of toxins that lead to various infections and diseases include; endotoxins and exotoxins and they are different based on their chemical nature. Exotoxin je toxin vylučovaný mikroorganismy, například bakteriemi, houbami, řasami a prvoky, do okolního prostředí. Exotoxiny mohou způsobovat poškození hostitele ničením jeho buněk nebo narušováním normálního buněčného metabolismu. Exotoxin A of Pseudomonas aeruginosa is a secreted bacterial toxin capable of translocating a catalytic domain into mammalian cells and inhibiting protein synthesis by the ADP-ribosylation of cellular elongation factor 2. The protein is a single polypeptide chain of 613 amino acids.

Ordet betyder bokstavligen "inre gift" men är till skillnad från exotoxiner inget som bakterierna aktivt utsöndrar.
