Function

Function:
Hydrolyzes the second messenger cAMP, which is a key regulator of many important physiological processes. May be involved in mediating central nervous system effects of therapeutic agents ranging from antidepressants to antiasthmatic and anti-inflammatory agents.
Pathway:
Purine metabolism; 3',5'-cyclic AMP degradation; AMP from 3',5'-cyclic AMP: step 1/1.
Catalytic Activity:
Adenosine 3',5'-cyclic phosphate + H(2)O = adenosine 5'-phosphate.
Cofactor:
COFACTOR: Name=a divalent metal cation; Xref=ChEBI:CHEBI:60240;
Enzyme Regulation:
ENZYME REGULATION: Inhibited by rolipram.
Active Site:
ACT_SITE 406 406 Proton donor.
