In enzymology, a hydroxyisourate hydrolase () is an enzyme that catalyzes the chemical reaction :5-hydroxyisourate + H2O 5-hydroxy-2-oxo-4-ureido-2,5-dihydro-1H-imidazole-5-carboxylate Thus, the two substrates of this enzyme are 5-hydroxyisourate and H2O, whereas its product is 5-hydroxy-2-oxo-4-ureido-2,5-dihydro-1H-imidazole-5-carboxylate. This enzyme belongs to the family of hydrolases, those acting on carbon-nitrogen bonds other than peptide bonds, specifically in cyclic amides. The systematic name of this enzyme class is 5-hydroxyisourate amidohydrolase. Other names in common use include HIUHase, and 5-hydroxyisourate hydrolase. This enzyme participates in purine metabolism. ==Structural studies== As of late 2007, two structures have been solved for this class of enzymes, with PDB accession codes and . 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「hydroxyisourate hydrolase」の詳細全文を読む スポンサード リンク
