Citation | Journal: Science / Year: 2019Title: The structure of a membrane adenylyl cyclase bound to an activated stimulatory G protein. Authors: Chao Qi / Simona Sorrentino / Ohad Medalia / Volodymyr M Korkhov / ![]() Abstract: Membrane-integral adenylyl cyclases (ACs) are key enzymes in mammalian heterotrimeric GTP-binding protein (G protein)-dependent signal transduction, which is important in many cellular processes. ...Membrane-integral adenylyl cyclases (ACs) are key enzymes in mammalian heterotrimeric GTP-binding protein (G protein)-dependent signal transduction, which is important in many cellular processes. Signals received by the G protein-coupled receptors are conveyed to ACs through G proteins to modulate the levels of cellular cyclic adenosine monophosphate (cAMP). Here, we describe the cryo-electron microscopy structure of the bovine membrane AC9 bound to an activated G protein αs subunit at 3.4-angstrom resolution. The structure reveals the organization of the membrane domain and helical domain that spans between the membrane and catalytic domains of AC9. The carboxyl-terminal extension of the catalytic domain occludes both the catalytic and the allosteric sites of AC9, inducing a conformation distinct from the substrate- and activator-bound state, suggesting a regulatory role in cAMP production. #1: Journal: To Be PublishedTitle: The structure of a membrane adenylyl cyclase bound to an activated stimulatory G protein Authors: Qi C / Sorrentino S / Medalia O / Korkhov VM | |||||||||
