Chain A,B,C,D (ILVE_THEMA | P74921)

molecular function
	GO:0052656	L-isoleucine transaminase activity	Catalysis of the reaction: 2-oxoglutarate + L-isoleucine = (S)-3-methyl-2-oxopentanoic acid + L-glutamic acid.
	GO:0052654	L-leucine transaminase activity	Catalysis of the reaction: 2-oxoglutarate + L-leucine = 4-methyl-2-oxopentanoate + L-glutamatic acid.
	GO:0052655	L-valine transaminase activity	Catalysis of the reaction: 2-oxoglutarate + L-valine = 3-methyl-2-oxobutanoic acid + L-glutamatic acid.
	GO:0004084	branched-chain-amino-acid transaminase activity	Catalysis of the reaction: a branched-chain amino acid + 2-oxoglutarate = L-glutamate + a 2-oxocarboxylate derived from the branched-chain amino acid.
	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: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:0009082	branched-chain amino acid biosynthetic process	The chemical reactions and pathways resulting in the formation of amino acids containing a branched carbon skeleton, comprising isoleucine, leucine and valine.
	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:0009097	isoleucine biosynthetic process	The chemical reactions and pathways resulting in the formation of isoleucine, (2R,3R)-2-amino-3-methylpentanoic acid.
	GO:0009098	leucine biosynthetic process	The chemical reactions and pathways resulting in the formation of leucine, 2-amino-4-methylpentanoic 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.
	GO:0009099	valine biosynthetic process	The chemical reactions and pathways resulting in the formation of valine, 2-amino-3-methylbutanoic acid.
