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

1,4-alpha-glucan branching enzyme; Catalyzes the transfer of the phosphoribosyl group of 5- phosphorylribose-1-pyrophosphate (PRPP) to anthranilate to yield N-(5'- phosphoribosyl)-anthranilate (PRA).

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.

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.

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.

The glycosyl transferase family includes anthranilate phosphoribosyltransferase (TrpD, EC: 2.4.2.18) and thymidine phosphorylase (EC: 2.4.2.2). All these proteins can transfer a phosphorylated ribose substrate. Similar to sprot|YBIB_ECOLI (40%) and to sprot|TRPD_SULSO (25%). Pfam (PF02885): Glycosyl transferase, family 3; Family membership.

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

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.
