Protein involved in threonine synthase activity, pyridoxal phosphate binding and threonine biosynthetic process.

Acetolactate synthase 3 small subunit; Protein involved in acetolactate synthase activity and branched chain family amino acid biosynthetic process.

Pyridoxal phosphate-dependent threonine dehydratase protein; Protein involved in catalytic activity, pyridoxal phosphate binding and metabolic process.

Acetolactate synthase 3 large subunit; Protein involved in magnesium ion binding, acetolactate synthase activity, thiamine pyrophosphate binding, flavin adenine dinucleotide binding and branched chain family amino acid biosynthetic process.

Protein involved in thiamine pyrophosphate binding; Belongs to the TPP enzyme family.

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

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.

Protein involved in L-serine ammonia-lyase activity, 4 iron, 4 sulfur cluster binding and gluconeogenesis; Belongs to the iron-sulfur dependent L-serine dehydratase family.

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.
