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. 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.

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. Here, we report the discovery that bacteria also employ ADP-ribosylating toxins against each other during interspecies competition.

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.

We present a detailed picture of interactions between BECa and NADH, including bound water molecules located near the C1'-N glycosidic bond of NADH and the catalytically important ADP-ribosylating ADP‐ribosylation of host cell proteins is a common mode of cell intoxication by pathogenic bacterial toxins. Antibodies induced by immunization with inactivated ADP‐ribosylating toxins provide effici The cholixc toxin was dialyzed in 20 mM Tris-HCl, pH exotoxin (23), with similarity to exotoxin A (ExoA)6 of P. 7.6, 200 mM NaCl, and 0.1 mM phenylmethylsulfonyl fluoride and aeruginosa. ExoA is a potent ADP-ribosylating toxin that spe- was digested with tobacco etch virus (1:10 ratio) at 4 °C. 2014-12-31 An ADP-ribosylating toxin from Listeria monocytogenes is disclosed, together with mutant toxins and uses therefor.There is only a low level of sequence identity between this toxin and known toxins such as the iota toxin from Clostridium perfringens. 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.
