    8152   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. 
    8652   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. 
    9082   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. 
    9097   Isoleucine Biosynthetic Process  The Chemical Reactions and Pathways Resulting in the Formation of Isoleucine (2r* 3r*) 2 Amino 3 Methylpentanoic Acid. 
    9098   Leucine Biosynthetic Process  The Chemical Reactions and Pathways Resulting in the Formation of Leucine 2 Amino 4 Methylpentanoic Acid. 
    9316   3 Isopropylmalate Dehydratase Complex  A Heterodimeric Enzyme Complex Composed of Subunits Leuc and Leud. Catalyzes the Isomerization Between 2 Isopropylmalate and 3 Isopropylmalate Via the Formation of 2 Isopropylmaleate. 
    3861   3 Isopropylmalate Dehydratase Activity  Catalysis of the Reaction: 3 Isopropylmalate = 2 Isopropylmaleate + H2o. 
    16829   Lyase Activity  Catalysis of the Cleavage of C C C O C N and Other Bonds by Other Means Than by Hydrolysis or Oxidation or Conversely Adding a Group to a Double Bond. They Differ From Other Enzymes in That Two Substrates Are Involved in One Reaction Direction But Only One in the Other Direction. When Acting On the Single Substrate a Molecule Is Eliminated and This Generates Either a New Double Bond or a New Ring. 
    47508   (r) 2 Methylmalate Dehydratase Activity  Catalysis of the Reaction: (r) Citramalate = 2 Methylmaleate + H(2)o. 
    50075   Maleate Hydratase Activity  Catalysis of the Reaction: (r) Malate = H(2)o + Maleate.
