Protein

3',5'-cyclic adenosine monophosphate phosphodiesterase CpdA

Gene

cpdA

Organism
Pseudomonas aeruginosa
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Hydrolyzes cAMP to 5'-AMP. Plays an important regulatory role in modulating the intracellular concentration of cAMP, thereby influencing cAMP-dependent processes. Specifically required for regulation of virulence factors. Can also hydrolyze cGMP.UniRule annotation1 Publication

Catalytic activityi

Adenosine 3',5'-cyclic phosphate + H2O = adenosine 5'-phosphate.UniRule annotation1 Publication

Cofactori

a divalent metal cationUniRule annotation1 PublicationNote: Binds 2 metal cations per subunit. Site 1 may preferentially bind Fe3+ ions, while site 2 may have a preference for Fe2+ ions.UniRule annotation1 Publication

Enzyme regulationi

Activated by iron. Other divalent metal ions have no effect.1 Publication
