title: Solubilization of adenylate cyclase from normal and Rous sarcoma-transformed chicken embryo fibroblasts.
abstract: Adenylate cyclase activities in membranes prepared from Rous sarcoma-transformed chicken embryo fibroblasts are 2 to 4 times lower than in membranes prepared from normal chicken embryo fibroblasts. Adenylate cyclase activities were solubilized from normal and transformed membranes with five different nonionic detergents. In all cases, the specific activities of the enzyme solubilized from normal and transformed preparations were essentially identical. These data suggest that the microenvironment of adenylate cyclase in transformed membranes may be wholly or partially responsible for the decreased activities of this enzyme.
