In enzymology, a diphosphoinositol-pentakisphosphate kinase () is an enzyme that catalyzes the chemical reaction :ATP + 1D-myo-inositol 5-diphosphate pentakisphosphate ADP + 1D-myo-inositol bisdiphosphate tetrakisphosphate (isomeric configuration unknown) Thus, the two substrates of this enzyme are ATP and 1D-myo-inositol 5-diphosphate pentakisphosphate, whereas its 3 products are ADP, 1D-myo-inositol bisdiphosphate tetrakisphosphate and (isomeric configuration unknown). This enzyme belongs to the family of transferases, specifically those transferring phosphorus-containing groups (phosphotransferases) with a phosphate group as acceptor. The systematic name of this enzyme class is ATP:1D-myo-inositol-5-diphosphate-pentakisphosphate phosphotransferase. Other names in common use include PP-IP5 kinase, diphosphoinositol pentakisphosphate kinase, and ATP:5-diphospho-1D-myo-inositol-pentakisphosphate phosphotransferase. ==References== * * 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「Diphosphoinositol-pentakisphosphate kinase」の詳細全文を読む スポンサード リンク
