Chain A,B   (LEU1_MYCTU | P9WQB3)
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:0000287    magnesium ion binding    Interacting selectively and non-covalently with magnesium (Mg) ions.
    GO:0030145    manganese ion binding    Interacting selectively and non-covalently with manganese (Mn) ions.
    GO:0030955    potassium ion binding    Interacting selectively and non-covalently with potassium (K+) ions.
    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.
    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.
    GO:0008270    zinc ion binding    Interacting selectively and non-covalently with zinc (Zn) ions.
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:0040007    growth    The increase in size or mass of an entire organism, a part of an organism or a cell.
    GO:0009098    leucine biosynthetic process    The chemical reactions and pathways resulting in the formation of leucine, 2-amino-4-methylpentanoic acid.
cellular component
    GO:0005576    extracellular region    The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite.
    GO:0005886    plasma membrane    The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
