Inositol-hexakisphosphate kinase (EC 2.7.4.21, ATP:1D-myo-inositol-hexakisphosphate phosphotransferase) is an enzyme with systematic name ATP:1D-myo-inositol-hexakisphosphate 5-phosphotransferase.[1][2][3] This enzyme catalyses the following chemical reaction
- (1) ATP + 1D-myo-inositol hexakisphosphate
ADP + 1D-myo-inositol 5-diphosphate 1,2,3,4,6-pentakisphosphate - (2) ATP + 1D-myo-inositol 1,3,4,5,6-pentakisphosphate ADP + 1D-myo-inositol diphosphate tetrakisphosphate (isomeric configuration unknown)
Three mammalian isoforms are known to exist.
