These sequences are functionally identified as members of the adenylate cyclase family, which catalyses the conversion of ATP to 3',5'-cyclic AMP and pyrophosphate. Six distinct non-homologous classes of AC have been identified. The structure of three classes of adenylyl cyclases have been solved [3].	Domain
