Threonine synthase; Catalyzes the formation of L-threonine from O-phospho-L-homoserine; Derived by automated computational analysis using gene prediction method: Protein Homology.

Acetolactate synthase 3 catalytic subunit; Catalyzes the formation of 2-acetolactate from pyruvate, leucine sensitive; Derived by automated computational analysis using gene prediction method: Protein Homology.

Thiamine pyrophosphate-binding protein; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the TPP enzyme family.

Branched-chain amino acid aminotransferase; Acts on leucine, isoleucine and valine. Belongs to the class-IV pyridoxal-phosphate-dependent aminotransferase family.

Tryptophan synthase subunit beta; The beta subunit is responsible for the synthesis of L- tryptophan from indole and L-serine.

Hypothetical protein; Derived by automated computational analysis using gene prediction method: Protein Homology.

Threonine dehydratase; Catalyzes the anaerobic formation of alpha-ketobutyrate and ammonia from threonine in a two-step reaction. The first step involved a dehydration of threonine and a production of enamine intermediates (aminocrotonate), which tautomerizes to its imine form (iminobutyrate). Both intermediates are unstable and short-lived. The second step is the nonenzymatic hydrolysis of the enamine/imine intermediates to form 2- ketobutyrate and free ammonia. In the low water environment of the cell, the second step is accelerated by RidA.

3-isopropylmalate dehydrogenase; Catalyzes the oxidation of 3-carboxy-2-hydroxy-4- methylpentanoate (3-isopropylmalate) to 3-carboxy-4-methyl-2- oxopentanoate. The product decarboxylates to 4-methyl-2 oxopentanoate.

Tryptophan synthase subunit alpha; The alpha subunit is responsible for the aldol cleavage of indoleglycerol phosphate to indole and glyceraldehyde 3-phosphate. Belongs to the TrpA family.
