PMID: 8057931 [Indexed for MEDLINE] Publication Types: Review; MeSH terms. ADP Ribose Transferases* Adenosine Diphosphate Ribose/metabolism* Bacterial Toxins/analysis Bacterial ADP-ribosyltransferase toxins (bARTTs) transfer ADP-ribose to eukaryotic proteins to promote bacterial pathogenesis. 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. ADP-ribosylating toxins have been the focus of intensive research for more than 30 years.

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. 1. Crit Rev Microbiol. 1985;11(4):273-98.

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 []

ADP-ribosylation is involved in the regulation of DNA repair, transcription, and other processes. The 18 human ADP-ribose transferases with diphtheria toxin With only a single amino acid replacement cholera toxin CTA1 can be rendered while the native ADP-ribosylating molecule is a strong mucosal adjuvant. New pertussis toxin (PT) mutants are described being immunologically active and Chiron Corporation, Detoxified mutants of bacterial ADP-ribosylating toxins Bakteriella toxiner — Vidare har C. Botulinum C3 ADP-ribosylater GTP-bindande proteiner Rho och Ras och Pertussis-toxin ADP-Ribosylates Gi Chemical probes to study ADP-ribosylation: synthesis and biochemical as a potent but unselective inhibitor of diphtheria toxin-like ADP-ribosyltransferase 3 An ADP-ribosylating polypeptide produced by CORYNEBACTERIUM DIPHTHERIAE that causes the signs and symptoms of DIPHTHERIA.

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.

Among these virulence factors are three ADP-ribosylating AB-toxins, Plx1, Plx2, and C3larvin. Plx1 is a phage-born toxin highly homologous to the pierisin-like AB-toxins expressed by the whites-and-yellows family Pieridae (Lepidoptera, Insecta) and to scabin expressed by the …

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.

Aug 7, 2012 ADP-ribosylating toxins are usually secreted by bacterial pathogens in the host environment. Some of them, which possess arginine-specificity,

Actin is also ADP-ribosylated by the family of binary ADP-ribosylating toxins, including C2 toxin from C. botulinum and iota toxin from C. perfringens ( 9 ). 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 1994-01-01 · Photoaffinity Labeling of Active Site Residues in ADP-Ribosylating Toxins By STEPHEN F. CARROLL and R. JOHN COLLIER Introduction The ADP-ribosylating toxins are a class of enzymes which catalytically transfer the ADP-ribosyl moiety of NAD into covalent linkage with se- lected acceptor amino acids on specific target proteins (TP). ADP-ribosylating toxins have been the focus of intensive research for more than 30 years.
