Adenylate cyclase activity in Cyanobacteria: activation by Ca2+-calmodulin and a calmodulin-like activity

An adenylate cyclase activity was partially characterized in the cyanobacterium Anabaena sp. The enzyme activity is found in soluble cell fractions and shows an apparent molecular weight of about 183 400. This adenylate cyclase is activated by Ca2+ and bovine brain or spinach calmodulin and it is in...
