GMP-PNP | GMP-P(NH)P | Gpp(NH)p | Guanosine 5' | -(Beta,Gamma-Imido)Triphosphate | Guanyl-5' | -Imidodiphosphate | P(NH)PPG | Guanyl 5' | Imidodiphosphate | Imidodiphosphate, Guanylyl
A non-hydrolyzable analog of GTP, in which the oxygen atom bridging the beta to the gamma phosphate is replaced by a nitrogen atom. It binds tightly to G-protein in the presence of Mg2+. The nucleotide is a potent stimulator of adenylate cyclase. |
