Electron microscopic localization and hormonal (diiodotyrosine) induction of adenylate cyclase in the Tetrahymena.
Normal Tetrahymena cells exhibited adenylate cyclase activity exclusively in association with pinocytotic vesicles, whereas those treated with diiodotyrosine (T2) for growth stimulation showed it in association with the cell membrane, and intracellularly inside many dense bodies. It appears that hormonally activable adenylate cyclase is an inherent component of the Tetrahymena.
