In enzymology, an inositol 3-kinase (EC 2.7.1.64) is an enzyme that catalyzes the chemical reaction

ATP + myo-inositol ADP + 1D-myo-inositol 3-phosphate

Thus, the two substrates of this enzyme are ATP and myo-inositol, whereas its two products are ADP and 1D-myo-inositol 3-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:myo-inositol 1-phosphotransferase. Other names in common use include inositol-1-kinase (phosphorylating), myoinositol kinase, and myo-inositol 1-kinase. This enzyme participates in inositol phosphate metabolism.
