Indole-3-glycerol phosphate synthase (IGPS). catalytic activity:1-(2-carboxyphenylamino)-1-deoxy-d-ribulose 5-phosphate = 1-(indol-3-yl)glycerol 3-phosphate + co(2) + h(2)o. pathway: tryptophan biosynthesis; fourth step. InterPro: Indole-3-glycerol phosphate synthase; High confidence in function and specificity; Belongs to the TrpC family.

Anthranilate synthase component II (Glutamine amido-transferase). catalytic activity: chorismate + l-glutamine = anthranilate + pyruvate + l-glutamate. pathway: tryptophan biosynthesis; first step. TIGRFAM: trpG_papA: glutamine amidotransferase of anthranilate synthase or para-aminobenzoate synthase; High confidence in function and specificity.

Anthranilate synthase; 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 concentrations of ammonia.

Para-aminobenzoate synthase component I (EC 4.1.3.-) (ADC synthase). CATALYZES THE BIOSYNTHESIS OF 4-AMINO-4-DEOXYCHORISMATE (ADC) FROM CHORISMATE AND GLUTAMINE. InterPro: Anthranilate synthase component I and chorismate binding enzyme pabB: para-aminobenzoate synthase component I; Specificity unclear.

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

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

Bifunctional chorismate mutase/prephenate dehydratase P-protein, pheA,; High confidence in function and specificity.

AroC protein; Catalyzes the anti-1,4-elimination of the C-3 phosphate and the C-6 proR hydrogen from 5-enolpyruvylshikimate-3-phosphate (EPSP) to yield chorismate, which is the branch point compound that serves as the starting substrate for the three terminal pathways of aromatic amino acid biosynthesis. This reaction introduces a second double bond into the aromatic ring system.

Conserved hypothetical membrane protein. Homology to rsc2383 of R. solanacearum of 31% (trembl|Q8XWT7(SRS)). no domains predicted .no signal peptide. 1 TMHs; Conserved hypothetical protein.
