In enzymology, a cytosine deaminase () is an enzyme that catalyzes the chemical reaction :cytosine + H2O uracil + NH3 Thus, the two substrates of this enzyme are cytosine and H2O, whereas its two products are uracil and NH3. This enzyme belongs to the family of hydrolases, those acting on carbon-nitrogen bonds other than peptide bonds, specifically in cyclic amidines. The systematic name of this enzyme class is cytosine aminohydrolase. This enzyme is also called isocytosine deaminase. This enzyme participates in pyrimidine metabolism. ==Structural studies== As of late 2007, 13 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「cytosine deaminase」の詳細全文を読む スポンサード リンク
