Chain X (LEU1_LISMF | Q71Y35)

molecular function
	GO:0003852	2-isopropylmalate synthase activity	Catalysis of the reaction: 3-methyl-2-oxobutanoate + acetyl-CoA + H(2)O = (2S)-2-isopropylmalate + CoA + H(+).
	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: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.
	GO:0046912	transferase activity, transferring acyl groups, acyl groups converted into alkyl on transfer	Catalysis of the transfer of an acyl group from one compound (donor) to another (acceptor), with the acyl group being converted into alkyl on transfer.
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:0019752	carboxylic acid metabolic process	The chemical reactions and pathways involving carboxylic acids, any organic acid containing one or more carboxyl (COOH) groups or anions (COO-).
	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:0009098	leucine biosynthetic process	The chemical reactions and pathways resulting in the formation of leucine, 2-amino-4-methylpentanoic acid.
