Burr, Katja Stuber,† and Joachim Frey* Institute of Veterinary Bacteriology, University of Berne, CH-3012 Berne, Switzerland Received 14 February 2003/Accepted 26 August 2003 ADP-ribosyl transferase subunit of typhoid toxin from Salmonella typhi (exclusively human pathogen) is structurally similar to pertussis toxin; however, the pathogenic mechanisms as well as the proteins substrate(s) of this toxin remain unknown . The C2-like toxins from Clostridium sp. [44,250] and the newly characterized SpvB from Salmonella sp. Se hela listan på fr.wikipedia.org It is well known that a number of toxins produced by bacteria exert their action by ADP-ribosylating reaction to certain proteins which are essential for normal eukaryotic cellular functions. Most of these toxins are composed of two moieties, A and B. The ADP‐ribosylating toxins (ADPRTs) are a family of toxins that catalyse the hydrolysis of NAD and the transfer of the ADP‐ribose moiety onto a target. This family includes many notorious killers, responsible for thousands of deaths annually including: cholera, enterotoxic Escherichia coli , whooping cough, diphtheria and a plethora of Clostridial binary toxins.

In this minireview article, we discuss the structure and function of the bacterial ADP-ribosylating toxins including PEA and compare the differences particularly between PEA and other valevant toxins.

1985;11(4):273-98. ADP-ribosylating microbial toxins. Foster JW, Kinney DM. PMID: 2859967 [PubMed - indexed for MEDLINE] Bacterial ADP-ribosyltransferase toxins (bARTTs) transfer ADP-ribose to eukaryotic proteins to promote bacterial pathogenesis. Iota toxin produced by Clostridium perfringens is a binary, actin ADP-ribosylating toxin that is organized into the enzymatically active component Ia and the binding component Ib. Lipolysis-stimulated lipoprotein receptor (LSR) has been identified as a cellular receptor of Ib. Here, we investigated the [] These studies demonstrate that CARDS toxin-mediated ADP-ribosylation constitutes an important posttranslational modification of NLRP3, that ADPRT activity of CARDS toxin is essential for NLRP3 inflammasome activation, and that posttranslational ADPRT-mediated modification of the inflammasome is a newly discovered mechanism for inflammasome activation with subsequent release of IL-1β and associated pathologies.

In this Review, we use prototype bARTTs, such as diphtheria toxin and pertussis toxin, as references for the characterization of several new bARTTs from human, insect and plant pathogens, which were recently identified by bioinformatic analyses.

C2 toxin consists of the enzyme component C2I (431 amino acid residues, 49.3 kDa) and the binding/translocation component C2II (721 amino acid residues, 80.8 kDa). Cell biological studies were among the first to show the prototypical ADP-ribosylating toxin, diphtheria toxin, to form ion-conducting channels via a pH-triggered insertion of the translocation domains into host cells, which correlated with the ability of the toxin to translocate the catalytic domain into host cells. invariant in all ADP-ribosylating toxins.23,39−45 As proposed for Glu148 in DT, Glu553 in ETA, and Glu581 in CT, the glutamic acid is believed to stabilize the oxacarbenium intermediate after dissociation of nicotinamide by formation of a hydrogen bond with the 2′-OH of the ribose.30,46 The catalytic His is believed to form a hydrogen bond 2015-04-29 · Toxic component of a type II toxin-antitoxin (TA) system. Expression in E.coli inhibits cell growth; bacteriostasis is neutralized by expression of cognate antitoxin ParS. ADP-ribosylates E.coli ribose-phosphate pyrophosphokinase (RPPK, prs) using NAD(+) in vitro; ADP-ribosylates RPPK on 'Lys-182' and 'Ser-202'. Cannot use NADP(+). Preface.

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. 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.1 Publication 2018-11-15 · ADP-ribosylation of proteins can profoundly impact their function and serves as an effective mechanism by which bacterial toxins impair eukaryotic cell processes.
