Bordetella filamentous hemagglutinin and adenylate cyclase toxin interactions on the bacterial surface are consistent with FhaB-mediated delivery of ACT to phagocytic cells [PDF]
Bordetella species that cause respiratory infections in mammals include B. pertussis, which causes human whooping cough, and B. bronchiseptica, which infects nearly all mammals.

cAMP signaling of Bordetella adenylate cyclase toxin blocks M-CSF triggered upregulation of iron acquisition receptors on differentiating CD14+ monocytes [PDF]
Bordetella pertussis infects the upper airways of humans and disarms host defense by the potent immuno-subversive activities of its pertussis (PT) and adenylate cyclase (CyaA) toxins.

Bordetella Adenylate Cyclase Toxin Can Bind Ganglioside GM1
Adenylate cyclase toxin (CyaA) is produced by Bordetella pertussis, the causative agent of whooping cough. CyaA specifically binds to the heavily Nglycosylated β2 integrin receptor CD11b/CD18 on its main cellular target myeloid phagocytic cells.

Regulation of brain adenylate cyclase by calmodulin.
The roles of Ca$\sp{2+}$ and cAMP are central to stimulus-response coupling mechanisms in cells. Hence, interactions between these two second messengers may be important for the coordinate regulation of the intracellular mechanisms responsible for the ...

The authors use optical tweezers to show that the folding of repeats-in-toxin (RTX) block-iv in adenylate cyclase is templated by the folded RTX block-v. The findings suggest a possible mechanism for transmitting the folding signal in the RTX domain.

Anthrax edema factor toxicity is strongly mediated by the N-end rule. [PDF]
Anthrax edema factor (EF) is a calmodulin-dependent adenylate cyclase that converts adenosine triphosphate (ATP) into 3'-5'-cyclic adenosine monophosphate (cAMP), contributing to the establishment of Bacillus anthracis infections and the resulting ...

Differential regulation of actin-activated nucleotidyl cyclase virulence factors by filamentous and globular actin. [PDF]
Several bacterial pathogens produce nucleotidyl cyclase toxins to manipulate eukaryotic host cells. Inside host cells they are activated by endogenous cofactors to produce high levels of cyclic nucleotides (cNMPs).
