5'-Guanylyl imidodiphosphate (GDPNP) is a purine nucleotide. It is an analog of guanosine triphosphate in which one of the oxygen atoms is replaced with an amine, producing a non-hydrolyzable functional group. Guanylyl imidodiphosphate binds tightly to G-proteins in the presence of Mg2+.[2] Guanylyl imidodiphosphate is a potent stimulator of adenylate cyclase.[2] It is often used in studies of protein synthesis.[3][4]
