Identification of phosphodiesterase cAMP sensitive to calcium and calmodulin ions and its possible role in the process of tumour transformation of plant cells

Identification of phosphodiesterase cAMP sensitive to calcium and calmodulin ions and its possible role in the process of tumour transformation of plant cells
Interactions between 2 systems of secondary intermediaries, Ca2+-calmodulin and cAMP, in plant cells were studied at the level of a receptor enzyme, cAMP phosphodiesterase (PDE). A protein fraction containing PDE, sensitive to allosteric regulators, a complex of Ca2+-calmodulin and methylxanthines, was obtained. A dependence was demonstrated between Ca ion concn and intensity of the development of crown gall tumours using plant models with Agrobacterium tumefaciens.
