In enzymology, a diphthine synthase () is an enzyme that catalyzes the chemical reaction :S-adenosyl-L-methionine + 2-(3-carboxy-3-aminopropyl)-L-histidine S-adenosyl-L-homocysteine + 2-()-L-histidine Thus, the two substrates of this enzyme are S-adenosyl methionine and 2-(3-carboxy-3-aminopropyl)-L-histidine, whereas its two products are S-adenosylhomocysteine and )-L-histidine" TITLE="2-()-L-histidine">2-()-L-histidine. This enzyme belongs to the family of transferases, specifically those transferring one-carbon group methyltransferases. The systematic name of this enzyme class is S-adenosyl-L-methionine:2-(3-carboxy-3-aminopropyl)-L-histidine methyltransferase. Other names in common use include S-adenosyl-L-methionine:elongation factor 2 methyltransferase, and diphthine methyltransferase. ==Structural studies== As of late 2007, 84 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「Diphthine synthase」の詳細全文を読む スポンサード リンク
