3-dehydroquinate synthase; Catalyzes the conversion of 3-deoxy-D-arabino-heptulosonate 7-phosphate (DAHP) to dehydroquinate (DHQ); Belongs to the sugar phosphate cyclases superfamily. Dehydroquinate synthase family.

Chorismate synthase; 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.

Anthranilate synthase; TrpG; with TrpE catalyzes the formation of anthranilate and glutamate from chorismate and glutamine; TrpG provides the glutamine amidotransferase activity; Derived by automated computational analysis using gene prediction method: Protein Homology.

Shikimate dehydrogenase; Involved in the biosynthesis of the chorismate, which leads to the biosynthesis of aromatic amino acids. Catalyzes the reversible NADPH linked reduction of 3-dehydroshikimate (DHSA) to yield shikimate (SA).

Transketolase; Catalyzes the formation of ribose 5-phosphate and xylulose 5-phosphate from sedoheptulose 7-phosphate and glyceraldehyde 3-phosphate; can transfer ketol groups between several groups; in Escherichia coli there are two tkt genes, tktA expressed during exponential growth and the tktB during stationary phase; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the transketolase family.

Anthranilate synthase; Derived by automated computational analysis using gene prediction method: Protein Homology.

Glucose-6-phosphate isomerase; Derived by automated computational analysis using gene prediction method: Protein Homology; Belongs to the GPI family.

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.

Transaldolase; Transaldolase is important for the balance of metabolites in the pentose-phosphate pathway.
