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

Indole-3-glycerol phosphate synthase; Belongs to the TrpC family.

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 [...]

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

Histidine biosynthesis bifunctional protein HisIE; Bifunctional protein; protein synonym:phosphoribosyl-AMP cyclohydrolase/phosphoribosyl-ATP pyrophosphatase; In the N-terminal section; belongs to the PRA-CH family.

Chorismate mutase/prephenate dehydratase; Bifunctional protein; protein synonym:P-protein.

Putative phosphoribosylformylglycinamidine synthase.

peptidyl-tRNA hydrolase; The natural substrate for this enzyme may be peptidyl-tRNAs which drop off the ribosome during protein synthesis. Belongs to the PTH family.
