The G protein alpha subunit binds guanyl nucleotide and is a weak GTPase. A set of residues that are unique to G-alpha as compared to its ancestor the Arf-like family form a ring of residues centered on the nucleotide binding site [3]. A Ggamma is found fused to an inactive Galpha in the Dictyostelium protein gbqA [3].

adenylate cyclase  M-CSA #58

Adenylate cyclase converts adenosine triphosphate (ATP) into cyclic adenosine monophosphate (cAMP), a ubiquitous second messenger that regulates many functions. Many signalling pathways triggered by hormones and other biological processes converge on and regulate the integral membrane enzyme, including those of the heterotrimeric GTP-binding proteins. There are over 30 related proteins, including bacterial and fungal adenylyl cyclases as well as guanylyl cyclases.
