Structural Basis of the Pore-Forming Toxin/Membrane Interaction [PDF]
With the rapid growth of antibiotic-resistant bacteria, it is urgent to develop alternative therapeutic strategies. Pore-forming toxins (PFTs) belong to the largest family of virulence factors of many pathogenic bacteria and constitute the most ...

Curcumin Inhibits Membrane-Damaging Pore-Forming Function of the β-Barrel Pore-Forming Toxin Vibrio cholerae Cytolysin [PDF]
Vibrio cholerae cytolysin (VCC) is a β-barrel pore-forming toxin (β-PFT). Upon encountering the target cells, VCC forms heptameric β-barrel pores and permeabilizes the cell membranes.

Structure and mechanism of the two-component α-helical pore-forming toxin YaxAB [PDF]
The Yersinia YaxAB system is a pore-forming toxin of so far unknown structure. Here authors present X-ray and cryo-EM to structures of individual subunits and of the YaxAB pore complex, and find that YaxA binds to membranes first and recruits YaxB for ...

Complete structures of the YenTc holotoxin prepore and pore reveal the evolutionary basis for chitinase incorporation into ABC toxins [PDF]
ABC toxins are toxin-translocating, pore-forming proteins found in a wide range of insecticidal bacteria and some mammalian pathogens. The Yersinia entomopahaga toxin complex (YenTc) belongs to a distinct subclass of ABC toxins, defined by a divergent ...

Programmed cellular necrosis mediated by the pore-forming alpha-toxin from Clostridium septicum. [PDF]
Programmed necrosis is a mechanism of cell death that has been described for neuronal excitotoxicity and ischemia/reperfusion injury, but has not been extensively studied in the context of exposure to bacterial exotoxins.

The pore structure of Clostridium perfringens epsilon toxin
Epsilon toxin (Etx) is a potent pore forming toxin (PFT) produced by Clostridium perfringens. Here authors show the cryo-EM structure of the Etx pore assembled on the membrane of susceptible cells and shed light on pore formation and mutant phenotypes.

Membrane Permeabilization by Pore-Forming RTX Toxins: What Kind of Lesions Do These Toxins Form?
Pore-forming toxins (PFTs) form nanoscale pores across target membranes causing cell death. The pore-forming cytolysins of the RTX (repeats in toxin) family belong to a steadily increasing family of proteins characterized by having in their primary ...
