COMPLEX OF GS-ALPHA WITH THE CATALYTIC DOMAINS OF MAMMALIAN ADENYLYL CYCLASE
Overview
The crystal structure of a soluble, catalytically active form of adenylyl, cyclase in a complex with its stimulatory heterotrimeric G protein alpha, subunit (Gsalpha) and forskolin was determined to a resolution of 2.3, angstroms. When P-site inhibitors were soaked into native crystals of the, complex, the active site of adenylyl cyclase was located and structural, elements important for substrate recognition and catalysis were, identified. On the basis of these and other structures, a molecular, mechanism is proposed for the activation of adenylyl cyclase by Gsalpha.
About this Structure
