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

Anthranilate synthase component I; Part of a heterotetrameric complex that catalyzes the two- step biosynthesis of anthranilate, an intermediate in the biosynthesis of L-tryptophan. In the first step, the glutamine-binding beta subunit (TrpG) of anthranilate synthase (AS) provides the glutamine amidotransferase activity which generates ammonia as a substrate that, along with chorismate, is used in the second step, catalyzed by the large alpha subunit of AS (TrpE) to produce anthranilate. In the absence of TrpG, TrpE can synthesize anthranilate directly from chorismate and high concentr [...]

Putative anthranilate phosphoribosyltransferase; Catalyzes the transfer of the phosphoribosyl group of 5- phosphorylribose-1-pyrophosphate (PRPP) to anthranilate to yield N-(5'- phosphoribosyl)-anthranilate (PRA).

Possible prolipoprotein diacylglyceryl transferase; Catalyzes the transfer of the diacylglyceryl group from phosphatidylglycerol to the sulfhydryl group of the N-terminal cysteine of a prolipoprotein, the first step in the formation of mature lipoproteins.; Belongs to the Lgt family.

EC_number=4.1.3.-; Similar to M. tuberculosis pabA, p-aminobenzoate synthase glutamine amidotransferase, TR:Q50183 (EMBL:Z70722) (232 aa); Fasta score E(): 0, 100.0% identity in 232 aa overlap (EMBL:AL123456) (232 aa); Fasta score E(): 0, 100.0% identity in 232 aa overlap and to Azospirillum brasilense trpG, anthranilate synthase component II, SW:TRPG_AZOBR (P26922) (196 aa); Fasta score E(): 0, 56.1% identity in 187 aa overlap. Previously sequenced as TR:Q50183. Contains Pfam match to entry PF00117 GATase, Glutamine amidotransferase class-I. Contains PS00442 Glutamine amidotransferase [...]

Serine hydroxymethyltransferase; Catalyzes the reversible interconversion of serine and glycine with tetrahydrofolate (THF) serving as the one-carbon carrier. This reaction serves as the major source of one-carbon groups required for the biosynthesis of purines, thymidylate, methionine, and other important biomolecules. Also exhibits THF-independent aldolase activity toward beta-hydroxyamino acids, producing glycine and aldehydes, via a retro-aldol mechanism.

Threonine deaminase; 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 (By similarity).
