In enzymology, an inositol-tetrakisphosphate 1-kinase () is an enzyme that catalyzes the chemical reaction :ATP + 1D-myo-inositol 3,4,5,6-tetrakisphosphate ADP + 1D-myo-inositol 1,3,4,5,6-pentakisphosphate Thus, the two substrates of this enzyme are ATP and 1D-myo-inositol 3,4,5,6-tetrakisphosphate, whereas its two products are ADP and 1D-myo-inositol 1,3,4,5,6-pentakisphosphate. 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-3,4,5,6-tetrakisphosphate 1-phosphotransferase. Other names in common use include 1D-myo-inositol-tetrakisphosphate 1-kinase, inositol-trisphosphate 6-kinase, 1D-myo-inositol-trisphosphate 6-kinase, ATP:1D-myo-inositol-1,3,4-trisphosphate 6-phosphotransferase, inositol-trisphosphate 5-kinase, 1D-myo-inositol-trisphosphate 5-kinase, and ATP:1D-myo-inositol-1,3,4-trisphosphate 5-phosphotransferase. This enzyme participates in inositol phosphate metabolism and phosphatidylinositol signaling system. ==Structural studies== As of late 2007, 3 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「Inositol-tetrakisphosphate 1-kinase」の詳細全文を読む スポンサード リンク
