WebApr 9, 2024 · Cholera exotoxin (choleragen), produced by Vibrio cholerae (inf). This exotoxin catalyzes the ADP-ribosylation of a host cell protein called Gs that turns the synthesis of a metabolic regulator molecule called cyclic AMP (cAMP) on and off. In this case, synthesis stays turned on. WebCholeragen similarly increases the sensitivity of cyclase to other peptide (ACTH, vasoactive intestinal polypeptide) and nonpeptide (catecholamines) hormones in this and other tissues. The rate of 125I-labeled glucagon-membrane dissociation is decreased about 2-fold in toxin-treated liver membranes.

WebIntroduction: Cholera toxin (also known as choleragen and sometimes abbreviated to CTX, Ctx or CT) is an AB5 multimeric protein complex secreted by the bacterium Vibrio cholerae. CTX is responsible for the massive, watery diarrhea characteristic of cholera infection. It is a member of the heat-labile enterotoxin family. WebThe second way is the binding of the toxin to a specific receptor on the cell. By binding, the toxin penetrates into the cytoplasm, where it affects physiological mechanisms. According to the target organs, we can divide toxins into. neurotoxins (botulinum toxin, tetanospasmin); enterotoxins (choleragen , E. coli toxins); WebCholera toxin has also been reported to ADP-ribosylate tubulin.
