Identified by match to protein family HMM PF00753.

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

Threonine ammonia-lyase, biosynthetic; 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.

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

NADH dehydrogenase I, C/D subunits; NDH-1 shuttles electrons from NADH, via FMN and iron-sulfur (Fe-S) centers, to quinones in the respiratory chain. The immediate electron acceptor for the enzyme in this species is believed to be ubiquinone. Couples the redox reaction to proton translocation (for every two electrons transferred, four hydrogen ions are translocated across the cytoplasmic membrane), and thus conserves the redox energy in a proton gradient; In the N-terminal section; belongs to the complex I 30 kDa subunit family.

Ribulose bisphosphate carboxylase, small subunit; Identified by similarity to GP:17646562; match to protein family HMM PF00101.

Putative succinate dehydrogenase, cytochrome b556 subunit; Identified by similarity to SP:P10446; match to protein family HMM PF01127.

Putative nonribosomal peptide synthetase; Identified by similarity to GP:9715733; match to protein family HMM PF00501; match to protein family HMM PF00550; match to protein family HMM TIGR01733; match to protein family HMM TIGR02353; Belongs to the ATP-dependent AMP-binding enzyme family.
