Enzyme Information
| 2.7.11.12 |
cGMP-dependent protein kinase.
based on mapping to UniProt Q13976
ATP + a protein = ADP + a phosphoprotein.
-!- cGMP is required to activate this enzyme. -!- The enzyme occurs as a dimer in higher eukaryotes. -!- The C-terminal region of each polypeptide chain contains the catalytic domain that includes the ATP and protein substrate binding sites. -!- This domain catalyzes the phosphorylation by ATP to specific serine or threonine residues in protein substrates. -!- The enzyme also has two allosteric cGMP-binding sites (sites A and B). -!- Binding of cGMP causes a conformational change that is associated with activation of the kinase. -!- Formerly EC 2.7.1.37.
