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
A	PF05235	CHAD domain (CHAD)	CHAD domain	The CHAD domain is an alpha-helical domain functionally associated with the Pfam:PF01928 domains. It has conserved histidines that may chelate metals [1].	Domain
