Anthrax toxin functions by altering levels of cAMP. The toxin also contains an edema factor, which requires the activity of calmodulin (CaM) for proper function. Based on this information, which of the following can you conclude?
A) The toxin alters cAMP dependent cell signaling.
B) Calcium levels affect the function of the edema factor.
C) Unlike other toxins, the anthrax toxin does not function by altering biochemical signaling.
D) A and B
E) A and C
Answer: D) A and B
