Enzyme Information
| 3.1.4.52 |
Cyclic-guanylate-specific phosphodiesterase.
based on mapping to UniProt P76129
Cyclic di-3',5'-guanylate + H(2)O = 5'-phosphoguanylyl(3'->5')guanosine.
-!- Inhibited by Ca(2+) and Zn(2+). -!- Linearizes cyclic di-3',5'-guanylate, the product of EC 2.7.7.65 and an allosteric activator of EC 2.4.1.12 rendering it inactive. -!- It is the balance between these two enzymes that determines the cellular level of cyclic di-3',5'-guanylate.
