Chain A,B,C,D   (GABT_ECOLI | P22256)
molecular function
    GO:0047298    (S)-3-amino-2-methylpropionate transaminase activity    Catalysis of the reaction: (S)-3-amino-2-methylpropanoate + 2-oxoglutarate = 2-methyl-3-oxopropanoate + L-glutamate.
    GO:0003867    4-aminobutyrate transaminase activity    Catalysis of the reaction: 4-aminobutanoate + amino group acceptor = succinate semialdehyde + amino acid.
    GO:0003992    N2-acetyl-L-ornithine:2-oxoglutarate 5-aminotransferase activity    Catalysis of the reaction: 2-oxoglutarate + N(2)-acetyl-L-ornithine = N-acetyl-L-glutamate 5-semialdehyde + 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: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:0042450    arginine biosynthetic process via ornithine    The chemical reactions and pathways resulting in the formation of arginine (2-amino-5-guanidinopentanoic acid) via the intermediate compound ornithine.
    GO:0009450    gamma-aminobutyric acid catabolic process    The chemical reactions and pathways resulting in the breakdown of gamma-aminobutyric acid (GABA, 4-aminobutyrate), an amino acid which acts as a neurotransmitter in some organisms.
    GO:0009448    gamma-aminobutyric acid metabolic process    The chemical reactions and pathways involving gamma-aminobutyric acid (GABA, 4-aminobutyrate), an amino acid which acts as a neurotransmitter in some organisms.
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.
