Asymmetric Unit(hide GO term definitions)

Chain A,B (IPPK_ARATH | Q93YN9)

molecular function
	GO:0005524	ATP binding	Interacting selectively and non-covalently with ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator.
	GO:0035299	inositol pentakisphosphate 2-kinase activity	Catalysis of the reaction: 1D-myo-inositol 1,3,4,5,6-pentakisphosphate + ATP = 1D-myo-inositol hexakisphosphate + ADP + 2 H(+).
	GO:0032942	inositol tetrakisphosphate 2-kinase activity	Catalysis of the reaction: 1D-myo-inositol tetrakisphosphate + ATP = 1D-myo-inositol pentakisphosphate (containing 2-phosphate) + ADP.
	GO:0016301	kinase activity	Catalysis of the transfer of a phosphate group, usually from ATP, to a substrate molecule.
	GO:0046872	metal ion binding	Interacting selectively and non-covalently with any metal ion.
	GO:0000166	nucleotide binding	Interacting selectively and non-covalently with a nucleotide, any compound consisting of a nucleoside that is esterified with (ortho)phosphate or an oligophosphate at any hydroxyl group on the ribose or deoxyribose.
	GO:0016740	transferase activity	Catalysis of the transfer of a group, e.g. a methyl group, glycosyl group, acyl group, phosphorus-containing, or other groups, from one compound (generally regarded as the donor) to another compound (generally regarded as the acceptor). Transferase is the systematic name for any enzyme of EC class 2.
biological process
	GO:0030643	cellular phosphate ion homeostasis	Any process involved in the maintenance of an internal steady state of phosphate ions at the level of a cell.
	GO:0042742	defense response to bacterium	Reactions triggered in response to the presence of a bacterium that act to protect the cell or organism.
	GO:0050832	defense response to fungus	Reactions triggered in response to the presence of a fungus that act to protect the cell or organism.
	GO:0051607	defense response to virus	Reactions triggered in response to the presence of a virus that act to protect the cell or organism.
	GO:0040007	growth	The increase in size or mass of an entire organism, a part of an organism or a cell.
	GO:0048527	lateral root development	The process whose specific outcome is the progression of the lateral root over time, from its formation to the mature structure. A lateral root is one formed from pericycle cells located on the xylem radius of the root, as opposed to the initiation of the main root from the embryo proper.
	GO:0010264	myo-inositol hexakisphosphate biosynthetic process	The chemical reactions and pathways resulting in the formation of phytic acid, myo-inositol hexakisphosphate, a regulator of intracellular signaling, a highly abundant animal anti-nutrient and a phosphate and mineral storage compound in plant seeds.
	GO:0055062	phosphate ion homeostasis	Any process involved in the maintenance of an internal steady state of phosphate ions within an organism or cell.
	GO:0016310	phosphorylation	The process of introducing a phosphate group into a molecule, usually with the formation of a phosphoric ester, a phosphoric anhydride or a phosphoric amide.
cellular component
	GO:0005737	cytoplasm	All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
	GO:0005634	nucleus	A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.
