Function

Function:
Cyclic nucleotide phosphodiesterase with a dual-specificity for the second messengers cAMP and cGMP, which are key regulators of many important physiological processes. Has a higher affinity for cGMP than for cAMP.
Catalytic Activity:
Nucleoside 3',5'-cyclic phosphate + H(2)O = nucleoside 5'-phosphate.
Cofactor:
COFACTOR: Name=a divalent metal cation; Xref=ChEBI:CHEBI:60240;
Enzyme Regulation:
ENZYME REGULATION: Type I PDE are activated by the binding of calmodulin in the presence of Ca(2+).
Active Site:
ACT_SITE 219 219 Proton donor.
