In enzymology, a 1-phosphatidylinositol 4-kinase () is an enzyme that catalyzes the chemical reaction :ATP + 1-phosphatidyl-1D-myo-inositol ADP + 1-phosphatidyl-1D-myo-inositol 4-phosphate Thus, the two substrates of this enzyme are ATP and 1-phosphatidyl-1D-myo-inositol, whereas its two products are ADP and 1-phosphatidyl-1D-myo-inositol 4-phosphate. This enzyme belongs to the family of transferases, specifically those transferring phosphorus-containing groups (phosphotransferases) with an alcohol group as acceptor. The systematic name of this enzyme class is ATP:1-phosphatidyl-1D-myo-inositol 4-phosphotransferase. Other names in common use include phosphatidylinositol kinase (phosphorylating), phosphatidylinositol 4-kinase, phosphatidylinositol kinase, type II phosphatidylinositol kinase, PI kinase, and PI 4-kinase. This enzyme participates in inositol phosphate metabolism and phosphatidylinositol signaling system. ==Structural studies== As of late 2007, the structure has only been solved for this enzyme. Part of the enzyme was crystallized with its activating partner frequenin. 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「1-phosphatidylinositol 4-kinase」の詳細全文を読む スポンサード リンク
