General annotation (Comments)

Function

Hydrolyzes cAMP to 5'-AMP. Plays an important regulatory role in modulating the intracellular concentration of cAMP, thereby influencing cAMP-dependent processes. Specific for cAMP. Ref.1

Catalytic activity

Adenosine 3',5'-cyclic phosphate + H2O = adenosine 5'-phosphate. Ref.1

Cofactor

Binds 2 metal cations per subunit By similarity. HAMAP MF_00905

Enzyme regulation

Activated by iron. Ref.1

Sequence similarities

Belongs to the cAMP phosphodiesterase class-III family.

Biophysicochemical properties

Kinetic parameters:

KM=0.5 mM for cAMP Ref.1

Vmax=2.0 µmol/min/mg enzyme

Sequence caution

The sequence AAA69200.1 differs from that shown. Reason: Erroneous initiation.
