Protein

3',5'-cyclic adenosine monophosphate phosphodiesterase CpdA

Gene

cpdA

Organism
Pseudomonas aeruginosa
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-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

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
