cyc−-Variants of S49 lymphoma cells are defective in the stimulatory guanine nucleotide site of the adenylate cyclase but contain an inhibitory site. Treatment of cyc−cells with islet-activating protein (IAP), which causes ADP-ribosylation of anMr40 000 polypeptide in cyc−membranes, abolishes adenylate cyclase inhibition by GTP and the peptide hormone, somatostatin, but not that induced by GTPγS. Furthermore, somatostatin-induced stimulation of GTP hydrolysis is lost. Thus, the data indicate that IAP interferes with the adenylate cyclase system by an action at the inhibitory guanine nucleotide site.
