Chain A   (HXK_SCHMA | Q26609)
molecular function
    GO:0005524    ATP binding    Interacting selectively and non-covalently with ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator.
    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: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: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: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: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: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:0005623    cell    The basic structural and functional unit of all organisms. Includes the plasma membrane and any external encapsulating structures such as the cell wall and cell envelope.
