Biology:dGTPase
From HandWiki
Short description: Enzyme
The enzyme dGTPase (EC 3.1.5.1)[1][2] catalyzes the reaction
- dGTP + H2O [math]\displaystyle{ \rightleftharpoons }[/math] deoxyguanosine + triphosphate
This enzyme belongs to the family of hydrolases, specifically those acting on triphosphoric monoester bonds. The systematic name is dGTP triphosphohydrolase. Other names in common use include deoxy-GTPase, deoxyguanosine 5-triphosphate triphosphohydrolase, deoxyguanosine triphosphatase, and deoxyguanosine triphosphate triphosphohydrolase. This enzyme participates in purine metabolism.
Structural studies
As of late 2007, 4 structures have been solved for this class of enzymes, with PDB accession codes 1HA3, 2C77, 2C78, and 2DQB.
