Adenylate cyclase toxin from Bordetella pertussis is a 1706 amino acid residue long protein.The protein consists of three domains: from the N-terminus up to roughly residue 400, there is an adenylate-cyclase domain; between residues 500 and 700, there is a hydrophobic domain; and from residue 1000 to the C-terminus, there are calcium binding repeats.
