General annotation (Comments)

Function	Dual specificity cAMP and cGMP phosphodiesterase with marked preference for cyclic AMP, which is activated by cAMP and cGMP. Likely functions as a cAMP-stimulated cAMP-phosphodiesterase which may play a role in regulating the cAMP relay response. Ref.2 Ref.5 Ref.6
Catalytic activity	Adenosine 3',5'-cyclic phosphate + H2O = adenosine 5'-phosphate. Guanosine 3',5'-cyclic phosphate + H2O = guanosine 5'-phosphate.
Cofactor	Divalent metal cation. Can use manganese and to a lower extent magnesium and zinc. Half-maximal activation occurs between 10 and 100 µM of manganese whereas maximal activation occurs with 10 mM of zinc or magnesium. Ref.2
Subcellular location	Cytoplasm › cytosol Probable.
Developmental stage	Low expression during growth. Mainly expressed after 8-10 hours of starvation when cells are aggregating and in the multicellular stage. Ref.2 Ref.5 Ref.6
Domain	The beta lactamase-like domain catalyzes the hydrolysis of cGMP By similarity.
Sequence similarities	Belongs to the metallo-beta-lactamase superfamily. cNMP phosphodiesterase family. Contains 2 cyclic nucleotide-binding domains.
Biophysicochemical properties	Kinetic parameters: cAMP/cGMP selectivity of 9. KM=200 µM for cAMP KM=800 µM for cGMP Vmax=650 nmol/min/mg enzyme with cAMP as substrate Vmax=300 nmol/min/mg enzyme with cGMP as substrate pH dependence: Optimum pH is 7.0.
