ADP-ribosylating toxins have been the focus of intensive research for more than 30 years. Researchers from diverse fields of science have taken an interest in these bacterial toxins; they are studied, for example, by microbiologists, biochemists, cell biologists, and pharmacologists.

There are two principal reasons for the broad and still growing 1994-01-01 2014-07-14 MTX 30–870 is the native form of the ADP-ribosylating toxin from B. sphaericus SSII-1, which lacks the putative signal sequence of 29 amino acids. The toxin is reportedly proteolytically cleaved into a 27-kDa N-terminal fragment and a 70-kDa C-terminal fragment ( We show that the unique bacterial ADP-ribosylating and vacuolating toxin produced by Mycoplasma pneumoniae and designated community-acquired respiratory distress syndrome (CARDS) toxin activates the NLRP3 inflammasome by colocalizing with the NLRP3 inflammasome and catalyzing the ADP-ribosylation of NLRP3. The observed pleiotropic effects are the result of the ability of S1 to ADP-ribosylate certain inhibitory α-subunits of heterotrimeric GTP-binding proteins (G-proteins) involved in a variety of signaling pathways. 2010-02-26 ADP-ribosylating toxins have been the focus of intensive research for more than 30 years. Researchers from diverse fields of science have taken an interest in these bacterial toxins; they are studied, for example, by microbiologists, biochemists, cell biologists, and pharmacologists. ADP-ribosylating bacterial toxins. Functional data demonstrate that CARDS TX binds phosphatidylcholine (PC) and sphingo-myelin (SM) specifically over other membrane lipids.

ADP-ribosylation is the addition of one or more ADP-ribose moieties to a protein. It is a reversible post-translational modification that is involved in many cellular processes, including cell signaling, DNA repair, gene regulation and apoptosis. Improper ADP-ribosylation has been implicated in some forms of cancer. It is also the basis for the toxicity of bacterial compounds such as cholera toxin, diphtheria toxin, and others.

2015-04-29 2015-04-21 2018-11-15 Acts as an ADP-ribosylating toxin, which may transfer the ADP-ribosyl group from NAD(+) to specific amino acids in target proteins. Elicits cytopathic effects in mammalian cells, such as disorganization and disruption of respiratory epithelial integrity in tracheal epithelium and vacuolization in the cytoplasm of CHO and HeLa cells. 2018-09-12 2021-02-16 The ADP-Ribosylating Toxin, AexT, from Aeromonas salmonicida subsp. salmonicida Is Translocated via a Type III Secretion Pathway Sarah E. Burr, Katja Stuber,† and Joachim Frey* Institute of Veterinary Bacteriology, University of Berne, CH-3012 Berne, Switzerland Received … ferases, which ADP-ribosylate Rho GTPases at Asn41 (6–8), and Pseudomonas aeruginosa exoenzyme S, which modifies Ras proteins at several arginine residues (9). Another member of the family of ADP-ribosylating toxins is the mosquitocidal toxin (MTX),1 which is produced by the low-toxicity strain SSII-1 of Bacillus sphaericus. The toxin is lethal 2008-10-01 2021-03-10 Because of the cytotoxic ADP-ribosylating nature of PEA, it has been suggested as a good candidate in the preparation of immunotoxins.

The ADP-ribosylation of a large panel of host proteins catalyzed by bacterial toxins leads to the interruption of cellular metabolic and regulatory pathways causing severe diseases [14] . ADP-ribosylation of proteins can profoundly impact their function and serves as an effective mechanism by which bacterial toxins impair eukaryotic cell pro-cesses. Here, we report the discovery that bacteria also employ ADP-ribosylating toxins against each other during interspecies competition.

ADP-Ribosylating Toxins (Current Topics in Microbiology and Immunology) Second, the ADP-ribosylating toxins provide potent and often unique pharmacological tools for the study of the physiological functions of their target proteins. The latter is especially the case with cholera and pertussis toxins, which both modify the IX-subunits of heterotrimeric G-proteins involved in signal transduction pathways. ADP-RIBOSYLATING TOXINS. A large family of toxins hydrolyzes the cofactor NAD to nicotinamide and ADP-ribose. The toxin then transfers the ADP-ribose fragment to an acceptor molecule, usually a protein that binds GTP. The target protein is locked into its GTP-binding conformation and cannot perform its normal role ( Fig. 21.6 ).
