Chain A,B   (HXK1_HUMAN | P19367)
molecular function
    GO:0005524    ATP binding    Interacting selectively and non-covalently with ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator.
    GO:0003824    catalytic activity    Catalysis of a biochemical reaction at physiological temperatures. In biologically catalyzed reactions, the reactants are known as substrates, and the catalysts are naturally occurring macromolecular substances known as enzymes. Enzymes possess specific binding sites for substrates, and are usually composed wholly or largely of protein, but RNA that has catalytic activity (ribozyme) is often also regarded as enzymatic.
    GO:0008865    fructokinase activity    Catalysis of the reaction: ATP + D-fructose = ADP + D-fructose 6-phosphate.
    GO:0004340    glucokinase activity    Catalysis of the reaction: ATP + D-glucose = ADP + D-glucose-6-phosphate.
    GO:0005536    glucose binding    Interacting selectively and non-covalently with the D- or L-enantiomer of glucose.
    GO:0004396    hexokinase activity    Catalysis of the reaction: ATP + D-hexose = ADP + D-hexose 6-phosphate.
    GO:0016301    kinase activity    Catalysis of the transfer of a phosphate group, usually from ATP, to a substrate molecule.
    GO:0019158    mannokinase activity    Catalysis of the reaction: ATP + D-mannose = ADP + D-mannose 6-phosphate.
    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:0016773    phosphotransferase activity, alcohol group as acceptor    Catalysis of the transfer of a phosphorus-containing group from one compound (donor) to an alcohol group (acceptor).
    GO:0005515    protein binding    Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
    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:0061621    canonical glycolysis    The glycolytic process that begins with the conversion of glucose to glucose-6-phosphate by glucokinase activity. Glycolytic processes are the chemical reactions and pathways resulting in the breakdown of a carbohydrate into pyruvate, with the concomitant production of a small amount of ATP.
    GO:0005975    carbohydrate metabolic process    The chemical reactions and pathways involving carbohydrates, any of a group of organic compounds based of the general formula Cx(H2O)y. Includes the formation of carbohydrate derivatives by the addition of a carbohydrate residue to another molecule.
    GO:0046835    carbohydrate phosphorylation    The process of introducing a phosphate group into a carbohydrate, any organic compound based on the general formula Cx(H2O)y.
    GO:0001678    cellular glucose homeostasis    A cellular homeostatic process involved in the maintenance of an internal steady state of glucose within a cell or between a cell and its external environment.
    GO:0072655    establishment of protein localization to mitochondrion    The directed movement of a protein to the mitochondrion or a part of the mitochondrion.
    GO:0051156    glucose 6-phosphate metabolic process    The chemical reactions and pathways involving glucose 6-phosphate, a monophosphorylated derivative of glucose with the phosphate group attached to C-6.
    GO:0015758    glucose transport    The directed movement of the hexose monosaccharide glucose into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
    GO:0006096    glycolytic process    The chemical reactions and pathways resulting in the breakdown of a carbohydrate into pyruvate, with the concomitant production of a small amount of ATP and the reduction of NAD(P) to NAD(P)H. Glycolysis begins with the metabolism of a carbohydrate to generate products that can enter the pathway and ends with the production of pyruvate. Pyruvate may be converted to acetyl-coenzyme A, ethanol, lactate, or other small molecules.
    GO:0019318    hexose metabolic process    The chemical reactions and pathways involving a hexose, any monosaccharide with a chain of six carbon atoms in the molecule.
    GO:0072656    maintenance of protein location in mitochondrion    Any process in which a protein is maintained in a specific location in a mitochondrion, and is prevented from moving elsewhere.
    GO:0008152    metabolic process    The chemical reactions and pathways, including anabolism and catabolism, by which living organisms transform chemical substances. Metabolic processes typically transform small molecules, but also include macromolecular processes such as DNA repair and replication, and protein synthesis and degradation.
    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:0005929    cilium    A specialized eukaryotic organelle that consists of a filiform extrusion of the cell surface and of some cytoplasmic parts. Each cilium is largely bounded by an extrusion of the cytoplasmic (plasma) membrane, and contains a regular longitudinal array of microtubules, anchored to a basal body.
    GO:0005829    cytosol    The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
    GO:0016020    membrane    A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
    GO:0045121    membrane raft    Any of the small (10-200 nm), heterogeneous, highly dynamic, sterol- and sphingolipid-enriched membrane domains that compartmentalize cellular processes. Small rafts can sometimes be stabilized to form larger platforms through protein-protein and protein-lipid interactions.
    GO:0005741    mitochondrial outer membrane    The outer, i.e. cytoplasm-facing, lipid bilayer of the mitochondrial envelope.
    GO:0005739    mitochondrion    A semiautonomous, self replicating organelle that occurs in varying numbers, shapes, and sizes in the cytoplasm of virtually all eukaryotic cells. It is notably the site of tissue respiration.
    GO:0097228    sperm principal piece    The segment of the sperm flagellum where the mitochondrial sheath ends, and the outer dense fibers (ODFs) associated with outer axonemal doublets 3 and 8 are replaced by the 2 longitudinal columns of the fibrous sheath (FS) which run the length of the principal piece and are stabilized by circumferential ribs. The principal piece makes up ~2/3 of the length of the sperm flagellum and is defined by the presence of the FS and of only 7 (rather than 9) ODFs which taper and then terminate near the distal end of the principal piece.
