In enzymology, an acetylornithine transaminase () is an enzyme that catalyzes the chemical reaction :N2-acetyl-L-ornithine + 2-oxoglutarate N-acetyl-L-glutamate 5-semialdehyde + L-glutamate Thus, the two substrates of this enzyme are N2-acetyl-L-ornithine and 2-oxoglutarate, whereas its two products are N-acetyl-L-glutamate 5-semialdehyde and L-glutamate. This enzyme belongs to the family of transferases, specifically the transaminases, which transfer nitrogenous groups. The systematic name of this enzyme class is N2-acetyl-L-ornithine:2-oxoglutarate 5-aminotransferase. Other names in common use include acetylornithine delta-transaminase, ACOAT, acetylornithine 5-aminotransferase, acetylornithine aminotransferase, N-acetylornithine aminotransferase, N-acetylornithine-delta-transaminase, N2-acetylornithine 5-transaminase, N2-acetyl-L-ornithine:2-oxoglutarate aminotransferase, succinylornithine aminotransferase, and 2-N-acetyl-L-ornithine:2-oxoglutarate 5-aminotransferase. This enzyme participates in urea cycle and metabolism of amino groups. It employs one cofactor, pyridoxal phosphate. ==Structural studies== As of late 2007, 6 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「Acetylornithine transaminase」の詳細全文を読む スポンサード リンク
