This domain is found in Oedema factor (EF), the exotoxin with adenylyl cyclase activity produced by Bacillus anthracis to increase the concentration of cyclic AMP in infected host cells and disrupts intracellular signalling pathways. EF consists of four domains: a PA-binding domain (PABD), two adenylate cyclase domains (ACD) and a helical domain (HD, this entry). HD moves and forms a large clamp that almost completely encircles EF's activator calmodulin (CaM), naturally present in host cells, stabilizing a disordered loop and leading to enzyme activation [1,4].
