Inositol-tetrakisphosphate 5-kinase
- Inositol-tetrakisphosphate 5-kinase
In enzymology, an inositol-tetrakisphosphate 5-kinase (EC number|2.7.1.140) is an enzyme that catalyzes the chemical reaction
:ATP + 1D-myo-inositol 1,3,4,6-tetrakisphosphate ADP + 1D-myo-inositol 1,3,4,5,6-pentakisphosphate
Thus, the two substrates of this enzyme are ATP and 1D-myo-inositol 1,3,4,6-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-1,3,4,6-tetrakisphosphate 5-phosphotransferase. This enzyme is also called 1D-myo-inositol-tetrakisphosphate 5-kinase. This enzyme participates in inositol phosphate metabolism and phosphatidylinositol signaling system.
