Chain A   (HIS8_ECOLI | P06986)
molecular function
    GO:0080130    L-phenylalanine:2-oxoglutarate aminotransferase activity    Catalysis of the reaction: L-phenylalanine + 2-oxoglutarate = phenylpyruvate + L-glutamate.
    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:0004400    histidinol-phosphate transaminase activity    Catalysis of the reaction: L-histidinol-phosphate + 2-oxoglutarate = 3-(imidazol-4-yl)-2-oxopropyl phosphate + L-glutamate.
    GO:0042802    identical protein binding    Interacting selectively and non-covalently with an identical protein or proteins.
    GO:0030170    pyridoxal phosphate binding    Interacting selectively and non-covalently with pyridoxal 5' phosphate, 3-hydroxy-5-(hydroxymethyl)-2-methyl4-pyridine carboxaldehyde 5' phosphate, the biologically active form of vitamin B6.
    GO:0008483    transaminase activity    Catalysis of the transfer of an amino group to an acceptor, usually a 2-oxo acid.
    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:0009058    biosynthetic process    The chemical reactions and pathways resulting in the formation of substances; typically the energy-requiring part of metabolism in which simpler substances are transformed into more complex ones.
    GO:0008652    cellular amino acid biosynthetic process    The chemical reactions and pathways resulting in the formation of amino acids, organic acids containing one or more amino substituents.
    GO:0000105    histidine biosynthetic process    The chemical reactions and pathways resulting in the formation of histidine, 2-amino-3-(1H-imidazol-4-yl)propanoic acid.
    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.
cellular component
    GO:0005829    cytosol    The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
