Template:Infobox enzyme The enzyme guanosine-3′,5′-bis(diphosphate) 3′-diphosphatase (EC 3.1.7.2)[1][2] catalyzes the reaction
- guanosine 3′,5′-bis(diphosphate) + H2O GDP + diphosphate
This enzyme belongs to the family of hydrolases, specifically those acting on diphosphoric monoester bonds. The systematic name is guanosine-3′,5′-bis(diphosphate) 3′-diphosphohydrolase. Other names in common use include guanosine-3′,5′-bis(diphosphate) 3′-pyrophosphatase, PpGpp-3'-pyrophosphohydrolase, and PpGpp phosphohydrolase. This enzyme participates in purine metabolism.
