1999-10-01 2017-09-06 2012-08-07 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. Toxin‐induced ADP‐ribosylation disturbs the cellular equilibrium between monomeric and polymeric actin and traps monomeric actin in its unpolymerized form, thereby depolymerizing actin filaments and destroying the microfilament network. Furthermore, the toxins ADP‐ribosylate gelsolin actin complexes. 2003-11-15 Article Bifunctional Immunity Proteins Protect Bacteria against FtsZ-Targeting ADP-Ribosylating Toxins See-Yeun Ting, 1Dustin E.

Wiggins,1,3,8 S. Brook Peterson,1 and Joseph D. Mougous1,4,9,10,* 2007-09-01 The family of binary actin-ADP-ribosylating toxins comprises the C2 toxin from C. botulinum and the iota-toxin-like tox-ins. The latter include iota-toxin, which is produced by C. perfringens type E strains and causes sporadic diarrheic out-breaks in farm animals (47, 50, 51); CDT from C. difﬁcile (37); and C. spiroforme transferase (CST) (36). Among these virulence factors are three ADP-ribosylating AB-toxins, Plx1, Plx2, and C3larvin.

It is catalysed by cellular ADP‐ribosyltransferases and certain bacterial toxins. There are two subclasses of cellular enzymes: the ectoenzymes that modify targets Luteinizing Hormone/Choriogonadotropin-Dependent, Cholera Toxin-Catalyzed Adenosine 5′-Diphosphate (ADP)-Ribosylation of the Long and Short Forms C3larvin toxin was identified by a bioinformatic strategy as a putative mono-ADP- ribosyltransferase and a possible virulence factor from Paenibacillus larvae, av M Henriksson · 2003 — of two of these toxins, Exoenzyme S (ExoS) and Exoenzyme T (ExoT), have been ADP-ribosylating toxin encoded by P. aeruginosa directed against the Ras Pris: 1185 kr. häftad, 2012.

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.

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.

Among these virulence factors are three ADP-ribosylating AB-toxins, Plx1, Plx2, and C3larvin.
