- ATP + 1D-myo-inositol 5-diphosphate pentakisphosphate ADP + 1D-myo-inositol bisdiphosphate tetrakisphosphate (isomeric configuration unknown)
Thus, the two substrates of this enzyme are ATP and 1D-myo-inositol 5-diphosphate pentakisphosphate, whereas its 3 products are ADP, 1D-myo-inositol bisdiphosphate tetrakisphosphate (isomeric, and configuration unknown).
This enzyme belongs to the family of transferases, specifically those transferring phosphorus-containing groups (phosphotransferases) with a phosphate group as acceptor. The systematic name of this enzyme class is ATP:1D-myo-inositol-5-diphosphate-pentakisphosphate phosphotransferase. Other names in common use include PP-IP5 kinase, diphosphoinositol pentakisphosphate kinase, and ATP:5-diphospho-1D-myo-inositol-pentakisphosphate phosphotransferase.
