Enzyme Information

3.1.4.53

3',5'-cyclic-AMP phosphodiesterase.

based on mapping to UniProt Q08499

Adenosine 3',5'-cyclic phosphate + H(2)O = adenosine 5'-phosphate.

-!- Specific for 3',5'-cAMP and does not hydrolyze other nucleoside 3',5'-cyclic phosphates such as cGMP (cf. EC 3.1.4.17 and EC 3.1.4.35). -!- It is involved in modulation of the levels of cAMP, which is a mediator in the processes of cell transformation and proliferation. -!- Formerly EC 3.1.4.n1.
