Molecular characterization of an RTX toxin determinant from Actinobacillus suis [PDF]

open access: yesInfection and Immunity, 1992
RTX cytolysins are a family of calcium-dependent, pore-forming, secreted toxins found in a variety of gram-negative bacteria. The prototypical member of this family is the alpha-hemolysin of Escherichia coli. The RTX genetic determinants from seven members of the family Pasteurellaceae, Pasteurella haemolytica, Actinobacillus actinomycetemcomitans, and

Membrane Restructuring by Bordetella pertussis Adenylate Cyclase Toxin, a Member of the RTX Toxin Family [PDF]

open access: yesJournal of Bacteriology, 2004
ABSTRACT Adenylate cyclase toxin (ACT) is secreted by Bordetella pertussis , the bacterium causing whooping cough. ACT is a member of the RTX (repeats in toxin) family of toxins, and like other members in the family, it may bind cell membranes and cause disruption of the permeability barrier, leading to ...
