Identifier, protein and gene names [?]

Identifier
CPDA
Protein name
RecName: Full=3',5'-cyclic adenosine monophosphate phosphodiesterase CpdA;
Short=3',5'-cyclic AMP phosphodiesterase;
Short=cAMP phosphodiesterase;
EC 3.1.4.53;
Gene name
cpdA

Comments [?]

Function Hydrolyzes cAMP to 5'-AMP. Plays an important regulatory role in modulating the intracellular concentration of cAMP, thereby influencing cAMP-dependent processes.
Catalytic activity RHEA:25277: 3',5'-cyclic AMP + H2O = AMP + H(+)
EC 3.1.4.53
Cofactor Fe(2+)
Note: Binds 2 Fe(2+) ions per subunit.
Similarity Belongs to the cyclic nucleotide phosphodiesterase class-III family.

Keywords [?]

cAMP
Hydrolase
Iron
Metal-binding
Nucleotide-binding
