In enzymology, an inositol-trisphosphate 3-kinase () is an enzyme that catalyzes the chemical reaction :ATP + 1D-myo-inositol 1,4,5-trisphosphate ADP + 1D-myo-inositol 1,3,4,5-tetrakisphosphate Thus, the two substrates of this enzyme are ATP and 1D-myo-inositol 1,4,5-trisphosphate, whereas its two products are ADP and 1D-myo-inositol 1,3,4,5-tetrakisphosphate. This enzyme participates in 3 metabolic pathways: inositol phosphate metabolism, calcium signaling pathway, and phosphatidylinositol signaling system. This enzyme has at least one effector, Calcium. == Nomenclature == 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:1D-myo-inositol-1,4,5-trisphosphate 3-phosphotransferase. Other names in common use include 1D-myo-inositol-trisphosphate 3-kinase, and Ins(1,4,5)P3 3-kinase. 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「Inositol-trisphosphate 3-kinase」の詳細全文を読む スポンサード リンク
