UniProtKB description:  Edema factor (EF), which constitutes one of the three proteins composing the anthrax toxin, causes edema in the host (PubMed:6285339, PubMed:2108958, PubMed:11807546). Acts as a calmodulin-dependent adenylyl cyclase by converting ATP to cAMP, leading to dramatic elevation of intracellular cAMP levels in the host, thereby causing edema (PubMed:6285339, PubMed:2108958, PubMed:11807546). EF is not toxic by itself and only acts as an edema factor when associated with protective antigen (PA) to form the edema toxin (EdTx) (PubMed:11553601, PubMed:2108958). Required for the survival of germinated spores within macrophages at the early stages of infection (PubMed:11737637).
