the hydrolysis-resistant gtp photoaffinity probe p3- ( 4-azidoanilido ) -p1-5 ' gtp ( aagtp ) can promote a similar persistent inhibition of adenylate cyclase , and , after removal of unbound aagtp and subsequent uv photolysis , aagtp is covalently linked to the 40-kda inhibitory gtp binding protein , gni ( inhibitory guanine nucleotide binding regulatory subunit of adenylate cyclase ) .
