Reconstitution of a light‐stimulated adenylate cyclase from retina and Neurospora crassa preparations: Characterization of the heterologous systems using normal and degenerative retinas

Adenylate cyclase catalytic subunits from Neurospora crassa membranes may interact with regulatory factors from membranes of bovine retinal rod outer segments (pretreated with N‐ethylmaleimide), reconstituting a heterologous system which, in the presence of light, is catalytically active in assay mi...
