Optimal conditions for activation of adenylate cyclase in membrane particles were studied. Enzyme activation with serotonin (5-hydroxytryptamine). NaF, and guanosine 5'-(3-O-thio)-triphosphate (GTP gamma S) was time-and temperature-dependent. Mg2+ was required for enzyme activation. Adenylate cyclase that was activated by NaF
