DESCRIPTION

Also known as IPPK_ARATH, IPK1. Phosphorylates Ins(1, 3, 4, 5, 6)P5 at position 2 to form Ins(1, 2, 3, 4, 5, 6)P6 (InsP6 or phytate). Phytate is a regulator of intracellular signaling, a highly abundant animal antinutrient, and a phosphate store in plant seeds. Also phosphorylates Ins(1, 3, 4, 6)P4 and Ins(1, 4, 5, 6)P4 to produce Ins(1, 2, 3, 4, 6)P5 and Ins(1, 2, 4, 5, 6)P5.
