摘要:Membranes of mouse L cells that contain adenylate cyclase [ATP pyrophosphate-lyase (cyclizing), EC 4.6.1.1 ] but lack beta-adrenergic receptors have been solubilized with Lubrol 12A9. Addition of such adenylate cyclase-containing extracts to beta-adrenergic receptor-replete membranes from adenylate cyclase-deficient S49 lymphoma cells results in the production of a catecholamine-sensitive adenylate cyclase system. The effects of beta-adrenergic agonists and antagonists on the reconstituted system reproduce those that are characteristic of the wild-type S49 lymphoma cell. The uncoupled variant of the S49lymphoma contains adenylate cyclase, but donor extracts from this clone fail to reconstitute the hormone-sensitive enzyme activity when added to adenylate cyclase-deficient membranes. Thus, the uncoupled and adenylate cyclase-deficient variants of the S49 cell are not complementary.
