In enzymology, an arginine deiminase () is an enzyme that catalyzes the chemical reaction :L-arginine + H2O L-citrulline + NH3 Thus, the two substrates of this enzyme are L-arginine and H2O, whereas its two products are L-citrulline and NH3. This enzyme belongs to the family of hydrolases, those acting on carbon-nitrogen bonds other than peptide bonds, specifically in linear amidines. The systematic name of this enzyme class is L-arginine iminohydrolase. Other names in common use include arginine dihydrolase, citrulline iminase, and L-arginine deiminase. This enzyme participates in arginine and proline metabolism. This enzyme is widely expressed in bacteria, including streptococcus and actinomyces. The bacterial arginine deiminase expression could be regulated by various environmental factors. ==Structural studies== As of late 2007, 7 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「Arginine deiminase」の詳細全文を読む スポンサード リンク
