In enzymology, a guanosine-3',5'-bis(diphosphate) 3'-diphosphatase () is an enzyme that catalyzes the chemical reaction :guanosine 3',5'-bis(diphosphate) + H2O guanosine 5'-diphosphate + diphosphate Thus, the two substrates of this enzyme are guanosine 3',5'-bis(diphosphate) and H2O, whereas its two products are guanosine 5'-diphosphate and diphosphate. This enzyme belongs to the family of hydrolases, specifically those acting on diphosphoric monoester bonds. The systematic name of this enzyme class 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. ==Structural studies== As of late 2007, only one structure has been solved for this class of enzymes, with the PDB accession code . 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Guanosine-3',5'-bis(diphosphate) 3'-diphosphatase」の詳細全文を読む スポンサード リンク
