In enzymology an inositol-pentakisphosphate 2-kinase (EC 2.7.1.158) is an enzyme that catalyzes the chemical reactionATP + 1D-myo-inositol 13456-pentakisphosphate ADP + 1D-myo-inositol hexakisphosphateThus the two substrates of this enzyme are ATP and 1D-myo-inositol 13456-pentakisphosphate whereas its two products are ADP and 1D-myo-inositol hexakisphosphate.This enzyme belongs to the family of transferases specifically those transferring phosphorus-containing groups (phosphotransferases) with an alcohol group as acceptor.
