obsolete inositol heptakisphosphate 4-kinase or 6-kinase activity (obsolete GO:0033199)
OBSOLETE. Catalysis of the reaction: ATP + 5-diphospho-1D-myo-inositol (1,2,3,4,6)pentakisphosphate = 4,5-bisdiphosphoinositol-1D-myoinositol (1,2,3,6)tetrakisphosphate, and ATP + 5-diphospho-1D-myo-inositol (1,2,3,4,6)pentakisphosphate = 5,6-bisdiphosphoinositol-1D-myoinositol (1,2,3,4)tetrakisphosphate.
