In enzymology, a 1-phosphatidylinositol-3-phosphate 5-kinase (EC 188.8.131.52) is an enzyme that catalyzes the chemical reactionATP + 1-phosphatidyl-1D-myo-inositol 3-phosphate ⇌ ADP + 1-phosphatidyl-1D-myo-inositol 3,5-bisphosphate
Thus, the two substrates of this enzyme are ATP and 1-phosphatidyl-1D-myo-inositol 3-phosphate, whereas its two products are ADP and 1-phosphatidyl-1D-myo-inositol 3,5-bisphosphate.
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-3-phosphate 5-phosphotransferase. Other names in common use include type III PIP kinase, and phosphatidylinositol 3-phosphate 5-kinase. This enzyme participates in phosphatidylinositol signaling system and regulation of actin cytoskeleton.
