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.
