the nature of the interaction of the metal ion and gtp at the nucleotide-binding site of transducin is discussed together with the results from previous studies using the phosphorothioate gtp analogues [ yamanaka , g. , eckstein , f. , & stryer , l. ( 1985 ) biochemistry 24 , 8094-8101 ] and is compared to the site found in homologous gtp-binding proteins such as elongation factor tu [ jurnak , f. ( 1985 ) science ( washington , d.c. ) 230 , 32-36 ; la cour , t.f.m. , nyborg , j. , thirup , s. , & clark , b.f.c . ( 1985 ) embo j . 4 , 2385-2388 ] .
