    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:0046500    S-adenosylmethionine metabolic process    The chemical reactions and pathways involving S-adenosylmethionine, S-(5'-adenosyl)-L-methionine, an important intermediate in one-carbon metabolism.
    GO:0006464    cellular protein modification process    The covalent alteration of one or more amino acids occurring in proteins, peptides and nascent polypeptides (co-translational, post-translational modifications) occurring at the level of an individual cell. Includes the modification of charged tRNAs that are destined to occur in a protein (pre-translation modification).
    GO:0005977    glycogen metabolic process    The chemical reactions and pathways involving glycogen, a polydisperse, highly branched glucan composed of chains of D-glucose residues in alpha-(1->4) glycosidic linkage, joined together by alpha-(1->6) glycosidic linkages.
    GO:0046487    glyoxylate metabolic process    The chemical reactions and pathways involving glyoxylate, the anion of glyoxylic acid, HOC-COOH.
    GO:0006555    methionine metabolic process    The chemical reactions and pathways involving methionine (2-amino-4-(methylthio)butanoic acid), a sulfur-containing, essential amino acid found in peptide linkage in proteins.
    GO:0032259    methylation    The process in which a methyl group is covalently attached to a molecule.
    GO:0006730    one-carbon metabolic process    The chemical reactions and pathways involving the transfer of one-carbon units in various oxidation states.
    GO:0051289    protein homotetramerization    The formation of a protein homotetramer, a macromolecular structure consisting of four noncovalently associated identical subunits.
    GO:0006111    regulation of gluconeogenesis    Any process that modulates the frequency, rate or extent of gluconeogenesis, the formation of glucose from noncarbohydrate precursors, such as pyruvate, amino acids and glycerol.
cellular component
    GO:0005737    cytoplasm    All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
    GO:0005829    cytosol    The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
