Current Opinion in Structural Biology, 1995
Crystal structures of shiga and pertussis toxins have recently revealed a remarkable degree of structural homology among the members of the AB5 class of bacterial toxins. Other structures have provided a detailed view of the molecular basis of receptor binding specificity of cholera toxin, and of the heat-labile enterotoxin of Escherichia coli.

Epsilon toxin: a fascinating pore‐forming toxin
The FEBS Journal, 2011Epsilon toxin (ETX) is produced by strains of Clostridium perfringens classified as type B or type D. ETX belongs to the heptameric β‐pore‐forming toxins including aerolysin and Clostridium septicum alpha toxin, which are characterized by the formation of a pore through the plasma membrane of eukaryotic cells consisting in a β‐barrel of 14 amphipatic β

Clinical Reviews in Allergy, 1993
We have presented in some detail the more common clinical syndromes produced by the ingestion of natural seafood toxins, and touched on those that could be of interest to the international traveler and to the sport fisherman. For the practicing allergist, knowledge of this wide array of clinical syndromes of toxicity is of paramount importance for the ...

Cellular and Molecular Life Sciences (CMLS), 1999
Though its lethal effects were ascribed to an exotoxin almost half a century ago, the pathogenesis of anthrax has yet to be satisfactorily explained. Subsequent work has led to the molecular identification and enzymatic characterization of three proteins that constitute two anthrax toxins.

Toxicon, 2001
Shiga toxin and Shiga-like toxins belong to the group of protein toxins which have a moiety that binds to the cell surface and another enzymatically active moiety that after entry into the cytosol inhibits protein synthesis enzymatically. The toxins can also cause apoptosis by mechanisms that may be different from the effect on the protein synthesis ...

Annual Review of Cell and Developmental Biology, 2003
▪ Abstract Anthrax toxin consists of three nontoxic proteins that associate in binary or ternary combinations to form toxic complexes at the surface of mammalian cells. One of these proteins, protective antigen (PA), transports the other two, edema factor (EF) and lethal factor (LF), to the cytosol.

Molecular Nutrition & Food Research, 2006
AbstractBlue‐green algae are found in lakes, ponds, rivers and brackish waters throughout the world. In case of excessive growth such as bloom formation, these bacteria can produce inherent toxins in quantities causing toxicity in mammals, including humans. These cyanotoxins include cyclic peptides and alkaloids.

Toxins are produced by numerous microorganisms and invertebrates as well as by higher plants and animals. Venoms are produced by many groups of animals, from coelenterates to vertebrates. While toxins and venoms are the primary toxicological concern in natural ecosystems, they are frequently of importance in agroecosystems and in military deployments ...

Clinical Infectious Diseases, 1983
Few of the cellular components of group A streptococci appear to be directly toxic for animals or humans. Some preparations of M protein produce an immunotoxic effect on human platelets and neutrophils. Cell wall fragments produce a chronic multinodular inflammatory lesion of dermal connective tissue.
