FunFam 18: Phosphodiesterase

There are 2 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
3',5'-cyclic-AMP phosphodiesterase. [EC: 3.1.4.53]
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.
4 P0C1Q2 Q1KKS3 Q8VID6 Q9HCR9
3',5'-cyclic-GMP phosphodiesterase. [EC: 3.1.4.35]
Guanosine 3',5'-cyclic phosphate + H(2)O = guanosine 5'-phosphate.
