Staphylococcal alpha-toxin, binding possibly occurs to clustered phosphocholine head groups in cholesterol/sphingomyelin-rich membrane microdomains. Toxin heptamers can rapidly assemble at such sites, and oligomerization triggers conformational changes leading to insertion of an amphipathic hairpin b-barrel sequence into the

zymocin and other plasmid-encoded yeast killer toxins, inter-yeast pathogenesis. Molecularly, gene disruption and shuffle techniques have proven powerful means to study components essentially required for the maintenance of the killer plasmid system, namely, autonomously operating replication and transcription apparatuses. Moreover, by studying zymocin

The , killer toxins,They bear some similarity to other families of protein toxins, which are ubiquitous in nature. The three known . killer toxins typify, in many respects, the class of killer toxins. Two of them appear to exert their effects by affecting ion fluxes. Two are processed by a Golgi enzyme apparently extan

Ricin: structure, synthesis, and mode of action,tein synthesis. Structurally, ricin is a heterodimer comprised of an enzymatic polypeptide (the A chain) disulphide bonded to a cell-binding lectin (the B chain). After surface binding, the holotoxin is internalised to endosomes from where a small fraction can be transported by a retrograde route to
