CC -!- FUNCTION: Kinase that can phosphorylate various inositol polyphosphate
CC such as Ins(3,4,5,6)P4 or Ins(1,3,4)P3 and participates in phytic acid
CC biosynthesis in developing seeds. Phytic acid is the primary storage
CC form of phosphorus in cereal grains and other plant seeds.
CC {ECO:0000250|UniProtKB:Q84Y01}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=1D-myo-inositol 3,4,5,6-tetrakisphosphate + ATP = 1D-myo-

CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000250|UniProtKB:Q13572};
CC Note=Binds 2 magnesium ions per subunit.
CC {ECO:0000250|UniProtKB:Q13572};
