in our studies with purified soluble guanylate cyclase from rat lung , we have tested a number of guanosine 5'-triphosphate ( gtp ) analogues as substrates and inhibitors , 5'-guanylylimidodiphosphate ( gmp-p ( nh ) p ) , guanylyl ( beta , gamma-methylene ) diphosphate ( gmp-p ( ch2 ) p ) , and guanosine 5'-o- ( 3-thiotriphosphate ) ( gtp gamma s ) were found to be substrates for guanylate cyclase .
