[Adenyl cyclase and adenosine-3',5'-monophosphate phosphodiesteraze: their nature, properties and regulation].

Modern data on the nature, properties and pathways of regulation enzymes, participated metabolism of cyclic, adenosine-3',5'-monophosphate, are described. Much consideration is being given to the problem of regulation of the phosphodiesterase activity due to the effect of Ca2+-binding proteins.
