Escherichia coli K-12 substr. MG1655 Enzyme: guanylate cyclase

Summary:
There is no gene identified with the enzyme yet.

Gene-Reaction Schematic: ?


Enzymatic reaction of: guanylate cyclase

Synonyms: guanylyl cyclase, guanyl cyclase, GTP pyrophosphate-lyase (cyclizing)

EC Number: 4.6.1.2

GTP <=> cyclic-GMP + diphosphate

The reaction direction shown, that is, A + B ↔ C + D versus C + D ↔ A + B, is in accordance with the direction of enzyme catalysis.

This reaction is reversible.

Summary:
Guanylate cyclase catalyzes the synthesis of cyclic GMP. The enzyme is distinct from adenylate cyclase. [Macchia81] Its genetics are unknown.

Cofactors or Prosthetic Groups: Mn2+ [Comment 1]

Inhibitors (Unknown Mechanism): fluoride [Comment 2]
